Fire safety planning for the preservation of historic department store building as cultural asset - A case study on Nihonbashi Mitsukoshi Main Store

Hiroko Kazusa, Yuji Hasemi, Shin-Ichi Tsuchiya, Yoshikazu Minegishi

AIJ Journal of Technology and Design 24 ( 56 ) 207 - 210 2018.02

　View Summary

Numbers of commercial buildings built before WWII are now considered historic monuments, yet most of them scarcely comply with current prescriptive fire safety requirements. This report shows an example of fire safety design for the preservation of Nihonbashi Mitsukoshi Main Store as cultural asset. The building features various weakness in fire safety including large open void penetrating five floors, staircases not satisfying the evacuation requirement etc. The proposed design utilizes existing fire shutters dividing each floor into three fire compartments as temporary fire refuges to overcome the weakness without changing any important historic elements of the building.

Journal of Structural and Construction Engineering 82 ( 732 ) 299 - 308 2017.02

　View Summary

The mechanical properties of Cryptomeria Japonica, a softwood commonly used in timber engineering, and Zelkova serrata, a hardwood normally used in traditional large buildings, heated up to 95°C were measured at the elevated water content and temperatures as an engineering basis for the structural fire safety design of large-scale timber buildings. The results show that the Young's modulus of two species at the elevated water content and temperatures was largely affected by the water content over 5% and the heating temperatures 80°C or higher. The bending strength at normal temperature or higher was highly dependent on the water content, however two species showed different declining trends with the rise of water content and temperatures. The correlation between Young's modulus and bending strength of Cryptomeria Japonica and Zelkova serrate keep to the same with the rise of the water content and temperatures.

STUDY ON THE PREDICTION OF THE FIRE PROTECTION PERFORMANCE OF INSULATED WOODEN-WALLS BY SMALL-SCALE SPECIMENS

ITOGE Osamu, HASEMI Yuji, TSUKIDATE Tsukasa, SUZUKI Hirotaka

Journal of Environmental Engineering (Transactions of AIJ) 82 ( 733 ) 183 - 193 2017

　View Summary

 This study aims to establish the rational prediction of the fire protection performance of insulated wooden walls to reduce the full-scale fire tests. Series of small-scale furnace tests are conducted on various types of wall constructions with rock-wool insulation, the most stable practical insulation material.  The results of the fire tests and one-dimensional steady-state heat transfer calculation lead the following conclusion on the wooden insulated walls with rock-wool insulation.  Without cavity, the calculation can almost reproduce the temperature profile in the wall as the disadvantageous situation that temperature becomes higher in. And the engineering problems, to grasp the heat balance in cavity and to build calculation model of it, are left.  Fire protection performance is required flame insulation property, heat insulation property and non-damage ability in Japan's building standard act.  Heat insulation property can be predicted by checking thermal resistance. If insulated walls have thermal resistance bigger than 1.70m²K/W when heated for 45 minutes, or 2.10m²K/W when heated for 60 minutes, heat insulation property can be secured enough.  Heat insulation property is made a difference between when heated from indoor side and from outdoor side by cavity or the material which phase conversion happens in high temperature. In non-insulated wall, infilled insulated wall and additional insulated wall, heat insulation property become more disadvantageous when heated from indoor side than from outdoor side, with gypsum board as interior material. In addition, cavity acts on more advantageous against heat insulation property.  The time when combustion begins in the pillars depend on thermal resistance of external protection layer when heated from outdoor side, and depend on how long gypsum board delays temperature rise at around 100 degrees Celsius when heated from indoor side. Non-damage ability becomes more disadvantageous when heated from indoor side than from outdoor side in non-insulated wall and all insulated wall with rock-wool even if any constructing method.  The infilled insulation raises the back-surface temperature of the protection layer, also reduces the damage by protecting the side of the pillar. And the external insulation disturbs heat diffusion to the back side when heated from indoor side, also reduces the damage by protecting the front of the pillar when heated from outdoor side. Thus the infilled insulation and the external insulation have both advantageous factor and disadvantageous factor for non-damage ability. The combination of these factors can explain about non-damage ability in every constructing method of the insulated wall.  In addition, It is clarified that non-damage ability can be predicted by checking the back-surface temperature of the protection layer. This point suggests potential predictability by calculation, because the one-dimensional steady-state heat transfer calculation can almost reproduce the temperature profile, without cavity.

　View Summary

 Public buildings in Japan are being increasingly constructed from wood. Timber-based buildings have been considered from various perspectives, including management of forest resources and environment concern. Large-scale buildings in Japan are needed to be fire－resistive or quasi-fire-proof constructions to withstand fire damage. If a fire breaks out a large-scale timber building, the residual strength of structural members exposed to fire must be known for the fire safety. For this purpose, study on physical properties of wooden structural members are important and influence of charring, temperature shift under heating and water content at normal temperature of wooden structural members have been studied. However influence of water content on the structural properties of wooden members under high temperature is not clearly.  In this paper, Cryptomeria Japonica, a softwood commonly used in timber engineering, and Zelkova serrata, a hardwood normally used in traditional large buildings, were heated up to 95°C. The Young's modulus and bending strength of two species were measured at the elevated water content and temperatures. The results provide an engineering basis for the structural fire safety design of large-scale timber buildings. The following properties of the woods were analyzed and determined.  1. The effect of water content on Young's modulus and bending strength at elevated and normal temperatures.  2. The effect of heating on Young's modulus and bending strength at elevated water content.  3. Relationship between Young's modulus and bending strength in heated moisture state wood.  In the bending experiment, the mechanical properties of heated Cryptomeria Japonica and Zelkova serrate on a scale of 1 to 4 below water evaporation temperature (room temperature, 50°C, 80°C and 95°C). The specimens were hewed from the two logs without knot and sized 20mm square and 320mm span (Fig. 1). The water content of specimens was from 1 to 150% and divide into four groups. Group1 is low water content, under 5%, Group2 is medium water content, between 5% and 15%, Group3 is other medium water content, between 15% and 30%, Group4 is high water content, over 30%. We used, as needed, a small dry kiln heated to 60°C to drying. The bending test conformed to “The examination method for the bending strength” stipulated by JIS Z 2101 and was conducted in a compression testing machine with a heat-controlled chamber (Picture1). A flowchart of the experimental procedure is presented in Fig. 2.  The Young's modulus of two species at elevated water content and temperatures, was largely affected by water content over 5% and heating temperatures 80°C or higher. The bending strength at normal temperature or higher was highly dependent on water content, however two species show different declining trends with the rise of water content and temperatures. The correlation between Young's modulus and bending strength of Cryptomeria Japonica and Zelkova serrate keep to the same with the rise of water content and temperatures. This study reports an experimental assessment of structural fire safety on large-scale timber building.

Tomoyo Yamaguchi, Daisuke Kamikawa, Yuji Hasemi, Noboru Yasui, Ryo Takase, Masayuki Miyabayashi, Jun-Ichi Suzuki

Journal of Environmental Engineering (Japan) 81 ( 730 ) 1065 - 1074 2016.12

　View Summary

Strategy for the development of wooden fireproof structural elements based on the sacrifice-layer concept through bench-scale tests is studied through a series of bench scale tests on the design composed of sacrifice layer (chemically untreated wood), barrier (fire retardant treated wood) and loadbearing part (untreated wood). It has revealed importance of the design of the sacrifice layer to reach the glowing combustion temperature at around the end of the heating for the achievement of self-extinguishment. It has resulted in the development of Japanese-cedar based l"hour fireproof beam only with small test apparatuses available almost everywhere, demonstrating its advantage for the technical development in the districts not accessible to large furnaces.

Journal of Environmental Engineering (Japan) 81 ( 725 ) 625 - 632 2016.07

　View Summary

In this study we grasped about the priority of the disaster medical service of 14 disaster base hospitals and the necessary medical equipment and make a survey and analyze about electricity consumption accompanying with it, to estimate the appropriate capacity of a private power generator becoming necessary for correspondence at hospitals at the time of disaster. The obtained knowledge is shown below. The ratio of the private power generator to the contract demand of the 14 hospitals that the answer to the questionnaire was provided was from 43 to 155%, and considering the margin of the contract demand, most hospitals hold private power generators that has generation capacity of 60% degree of ordinary time. As a result of the medical equipment load that is assumed by each medical service contents at the time of the disaster calculated by per unit floor space, electricity consumption of emergency patient correspondence and the image diagnosis inspection were big , and the average electricity consumption of 5 hospitals were from 18.95 to 22.40 W/m2. From the results of estimating the medical equipment load corresponding to the priority of medical services, we found that the medical equipment load account for 51.8% to 120.4% of the capacity of private power generator and 44.5% to 86.3% of the contract demand, even performing duties only that has have the medical services also be always performed at the time of disaster.

　View Summary

 Recently, enrollments in nursery schools have become higher and higher. This is largely due to the social progress of women, with the increasing number of working mothers. Additionally, the number of three-generation households is decreasing. Nursery schools are traditionally low-rise structures, with a playground, but deregulation of the law now allows for the placement of nursery schools in middle floors of high-rise buildings. In Japan, the ages of nursery school students are generally from infancy to five-years old, which means that they can't evacuate the premises by themselves during a fire, so we must research ways to evacuate them safely. And the scheme of planning safe evacuations from buildings has not been sufficiently researched, so we have investigated the practice of fire drills and have interviewed teachers and students of nursery schools. The following is what we have learned:  (1)Characteristics of evacuation ;drills of nursery schools: Students evacuate in class groups, lead by their teachers, who provide the indications. Time is needed for evacuation preparation (setting up strollers, gathering infants and preparing to carry them out, and giving instructions regarding exiting, etc., ) and before starting evacuation, and time for confirming the numbers of students, and waiting time is needed when they are evacuating, so these times must be considered in the calculation of evacuation time.  (2)The characteristics of evacuation abilities of nursery school students : Infants (up to one-year old), and students who can't easily walk by themselves must be carried by a nurse or other adults, which makes evacuation movements and management after evacuation more manageable. Two-year-old students are able to walk alright on their own but cannot sufficiently grasp the situation. It's difficult to follow the teachers' instructions, so a lot of assistances are need. Children aged three and over can, of course, walk even better, and can grasp the severity of a fire. But they tend to walk more slowly as they feel frightened in cases when they are at earlier age, or they have to take an escape route that they are not familiar with. In order to shorten evacuation time, older students should evacuate first, as they can walk faster than younger students, thus their escape time won't be hindered by slower evacuees.  (3)Notes of buildings that include a nursery school: Regarding the situation of using stairways for evacuation, there are many points of concern regarding the safety of children. Because there are many dangerous points related to stairways, such as the fact that stairways often arouse fear in younger students during emergency evacuation, and as a result they walk more slowly. Consequently, older students try to pass the younger, slower students. Especially in cases when a nursery school is on a middle floor of a multi-use building, there is a possibility that confusion is caused among the evacuating children who walk slowly, along with their teachers, as evacuating people from other facilities mix with people evacuating from the nursery school. Thus, having a dedicated set of stairs for children is better. In addition, nursery schools that are in existing buildings that were not designed to accommodate nursery schools, have higher handles and the height of steps rise.  (4)Decreasing evacuation route length: Due to the fact that nursery school students' bodies and minds are not fully developed, their circumstances during a fire are more severe than those for adults. Thus, nursery schools should be on lower floors of buildings or should have their own buildings. Also the distance from the rooms to the temporary evacuation place should be as short as possible

　View Summary

 After the Great Hanshin Awaji Earthquake, the establishment of a regional medical system and a preparation of disaster medical system that is the establishment of the disaster base hospital. Medical facilities are needed to be actuating when the disaster occurs, and varieties of standards and guidelines of architecture and facilities has been established. To enforce medical services smooth enough when the disaster occurs, we need improvement projects that assume disaster medical services beforehand.  But, at a large scale earthquake such as the Great East Japan earthquake, a case which sufficient medical service was difficult to enforce because of the shortage such as water and fuel due to long-term passage of the lifeline in addition to the damage of building equipment and medical equipment even in disaster base hospital has been reported.  About the facility requirements that is based on the correspondence of the disaster, it is determined comprehensively based on expenses among the minimum capacity that is prescribed by Building Standard Act/the Fire Services Act and the capacity that is demanded from the activity assumption, but at the time of disaster there are many cases that caused restriction of medical services because of the restriction on use of medical equipment and the capacity lack of the private power generator, so it doesn’t mean that it is always decided appropriately.  Therefore in this study, we will grasp about the priority of the disaster medical service in the disaster base hospital and the necessary medical equipment and make a survey and analyze about electricity consumption accompanying with it, to estimate the appropriate capacity of a private power generator becoming necessary for correspondence at hospitals at the time of disaster. This study is intended to contribute to the development of the hospital plan which can carry out the medical service at the time of disasters smoothly, by calculating electric power load that is based on the medical policy at the time of a disaster assumed on every hospital.  In this study, we grasped about the priority of the disaster medical service of 14 disaster base hospitals and the necessary medical equipment and make a survey and analyze about electricity consumption accompanying with it, to estimate the appropriate capacity of a private power generator becoming necessary for correspondence at hospitals at the time of disaster. The obtained knowledge is shown below.  1.

Simulation Methodology for Coupled Fire-Structure Analysis: Modeling Localized Fire Tests on a Steel Column

Chao Zhang, Julio G. Silva, Craig Weinschenk, Daisuke Kamikawa, Yuji Hasemi

FIRE TECHNOLOGY 52 ( 1 ) 239 - 262 2016.01 [Refereed]

　View Summary

Advanced simulation methods are needed to predict the complex behavior of structures exposed to realistic fires. Fire dynamics simulator (FDS) is a computational fluid dynamics code, developed by NIST for fire related simulations. In recent years, there has been an increase in use of FDS for performance-based analysis in the area of structural fire research. This paper discusses the FDS-finite element method (FEM) simulation methodology for structural fire analysis. The general methodology is described and a validation study is presented. A data element used to transfer data from FDS to FEM codes, the adiabatic surface temperature, is discussed. A tool named fire-thermomechanical interface is applied to transfer data from FDS to ANSYS. A high temperature stress-strain model for structural steel developed by NIST is included in the FEM analysis. Compared to experimental results, the FDS-FEM method predicted both the thermal and structural responses of a steel column in a localized fire test. The column buckling time was predicted with a maximum error of 7.8%. Based on these results, this methodology has potential to be used in performance-based analysis.

VALIDATION OF THE SCALING LAWS FOR THE COMBUSTION EFFICIENCY OF A COMPARTMENT FIRE WITH SMALL OPENINGS

NAKAMURA Masatoshi, MICHIKOSHI Shintaro, HASEMI Yuji

J. Environ. Eng. 80 ( 714 ) 621 - 627 2015

　View Summary

The objective of this study was to validate the scaling laws for the combustion efficiency of a compartment fire with small openings. Two full-scale tests and one quarter-scale test were conducted by using compartments with dimensions of 2.4 m × 3.6 m × 2.4 m and 0.6 m × 0.9 m × 0.6 m, respectively. Including our previous test results, the measured combustion efficiencies in the full- and quarter-scale compartments showed good agreement, and it was confirmed that the scaling laws for combustion efficiency are effective for full-scale compartment fires when the scale ratio is at a quarter-scale or higher.

AIJ Journal of Technology and Design 21 ( 48 ) 873 - 878 2015

　View Summary

Development of tsunami evacuation building has become an issue in Japan. This paper is a report on planning issues on the basis of the actual use surveys of tsunami evacuation building in the Great East Japan Earthquake. There are a lot of areas without a building that has the structure and scale conditions. The target building decreases more when buildings are required to the stay. It is necessary to develop the method that tsunami evacuation buildings with different performance are located effectively. In addition, in order to make effective use of tsunami evacuation building, the evacuation training is required.

ON-SITE INVESTIGATION ON THE UTILIZATION AND DISASTER IMPACT OF TSUNAMI EVACUATION BUILDINGS AT THE GREAT EAST JAPAN EARTHQUAKE

AIJ Journal of Technology and Design 21 ( 47 ) 381 - 386 2015

　View Summary

Tsunami evacuation buildings were used in the Great East Japan Earthquake. This paper reports an investigation on the actual use and disaster impacts of the tsunami evacuation buildings. There were many cases that tsunami rises up higher than actual tsunami depth. This means that it is not enough that refuge floors are located just higher than the assumed tsunami depth. There were many cases that buildings were cut off by debris, subsidence and flooding. Tsunami evacuation buildings are for temporary refuge, but this means that it is necessary to assume the stay in tsunami evacuation buildings.

AIJ Journal of Technology and Design 21 ( 47 ) 145 - 150 2015

　View Summary

Sprinklers systems are well known as one of the most efficiently suppression tool in building fires, however it is apprehended that sprinkler sprays might disturb the stratified smoke layer during initial stage of fire. On the other hand, mechanical smoke exhaust system also is used to delay the descent of the interface between upper and lower layers and to secure the evacuee's safety in fire in the high-rise and large scale buildings. In this study, a series of full-scale experimental study was carried out to unveil the effect of the sprinkler sprays, the mechanical smoke exhaust system and the length of smoke curtain on the smoke layer height. As a result, the useful experimental data on their relation was reported for applying to a simulation model related to fire.

Experimental study on merged flame characteristics from multifire sources with wood cribs

Wenguo Weng, Daisuke Kamikawa, Yuji Hasemi

PROCEEDINGS OF THE COMBUSTION INSTITUTE 35 2597 - 2606 2015 [Refereed]

　View Summary

This paper describes a series of experiments that were carried out to study merged flame characteristics. A specially designed wood crib burner were operated with the square burner configurations of 2 by 2 and 3 by 3, and various separation distances of 0, 1.5, 3 and 5 cm. The heat release rate, the mass loss rate, the heat feedback from the flame to the fuel surface, and the radiative heat flux were measured. The corresponding combustion efficiency and pyrolysis efficiency are calculated. The experimental data of the radiative heat flux from the merged flame are compared with the computed values of an empirical model from a single fire. Experimental data show that bigger separation distance and more burners advance the combustion efficiency due to more entrained ambient air; however have no obvious effects on the pyrolysis progress. The overall trend of the computed radiative heat flux is similar to that of the experimental data for the merged flame; only the times of the computed peak radiative heat fluxes are always lower than those of the experimental data.

Journal of Structural and Construction Engineering 79 ( 701 ) 1065 - 1072 2014.07

　View Summary

Young's modulus and bending strength of 3 species of wood commonly used for engineered wood and Zelkova, hardwood normally used for traditional large building, heated up to 250°C are measured at the elevated temperature and after cooling to the room temperature as an engineering basis for the structural fire safety design and the reusability diagnosis of large-scale timber buildings. The results show the both properties, either at elevated temperature or after cooling, are highly dependent on exposed temperature for 150-200°C or higher, and correlation between the Young's modulus and the bending strength tends to become weaker with rise of exposed temperature. The bendmg strength at elevated temperature is found to converge while it is notably scattered at normal temperature.

FLAME HEIGHT AND THERMAL ENVIRONMENT OF FIRES IN A NON-COMBUSTIBLE SHAFT UNDER THE STACK EFFECT

NIU Xuemin, HASEMI Yuji, KAGIYA Koji

J. Environ. Eng. 79 ( 700 ) 469 - 477 2014

　View Summary

Shafts are essential, and play a significant role in high-rise buildings. Nevertheless, the adverse effect of the shaft, which increases flames spread rate in high-rise buildings under the stack effect, is accompanied with fire safety. This paper focuses on obtaining the theoretical flame height and thermal environment for fires in the shaft based on experimental information. Bench-scale experiments were carried out in a large, confined space to reveal the motion of the flame in a non-combustible shaft. It shows that flame height increase is due to the increase in co-flowing. Increasing either the aspect ratio or the areas of inlet enhances the co-flowing as well as the flame height. Flame height has been theoretically derived for fires in the shaft. It is a function of the dimensionless heat release rate which is affected by the aspect ratio, areas of inlet, burner diameter, ratio of the areas of the inlet to the areas of the outlet and heat release rate of fire source. Moreover, empirical correlations have been correlated as a function of the dimensionless location for gas temperature rises in the shaft and heat fluxes on the wall. Negligible re-radiation among the symmetry walls is the main reason for high flame spread rates.

EFFECT OF FLAME BUOYANCY ON VENT FLOWS IN FULLY-DEVELOPED COMPARTMENT FIRES

NAKAMURA Masatoshi, MICHIKOSHI Shintaro, KAMIKAWA Daisuke, HASEMI Yuji

J. Environ. Eng. 79 ( 705 ) 919 - 925 2014

　View Summary

The objective of this study is to discuss whether the flame buoyancy increases vent flows in fully-developed compartment fires. Vent flows of small-scale compartments with narrow frontages were measured. Different ceiling heights of the compartments were set to vary the work of flame buoyancy. Greater vent flows were observed under the conditions with high ceiling. Calculated vent flows were more consistent with experimental data when the effect of flame buoyancy was taken account in, compared with when it was not considered. It was concluded that the flame buoyancy had the effect on vent flows of these compartments.

　View Summary

The fire experiment was conducted in Tsukuba in February, 2012 for studying a feasibility of a large wooden building. The building went up in flames and a large number of firebrands were generated and transported by wind. After the experiment, firebrands deposited in every location were collected and each total mass was measured. Consequently, the extent of the firebrand deposition and the distributions of the firebrand deposition density were obtained. The measurements of projected mass and volume of each firebrand revealed that firebrand mass density and dimensions decreased with a distance from the fire.

AIJ Journal of Technology and Design 19 ( 43 ) 971 - 975 2013.10

　View Summary

In the fire safety design for hospitals, operating suite, ICUs and CCUs are normally protected from fire in adjacent areas by fire separation walls, yet achievement of smoke separation is questionable. This paper discusses feasibility of smoke separation in fire of operating suite, ICU and CCU from other hospital parts utilizing the positive pressure air-conditioning system routinely used for cleaning level control in these areas. The study reveals capability of the normal positive pressure air-conditioning to prevent penetration of smoke from adjacent fires.

　View Summary

Mobility of the patients and number of ward staff available for disaster management in hospital ward are investigated in a large comprehensive hospital in Tokyo consisting of 1020 beds using the physical records of respective patients. The mobility ratios show high daily fluctuation, weak seasonal change and strong dependence on medical departments. Most of patients in pediatrics system, psychiatry, and cranial nerve need assisted evacuation at the event of fire. The investigation has revealed restriction of the number of ward staff at night, which may need extensive reorganization of emergency management.

REDUCED SCALE TESTS ON COMBUSTION EFFICIENCY IN COMPARTMENT FIRE WITH SMALL OPENINGS

NAKAMURA Masatoshi, MICHIKOSHI Shintaro, HASEMI Yuji

J. Environ. Eng. 78 ( 690 ) 613 - 622 2013

　View Summary

The objectives of this study are to investigate the relationship between the combustion efficiency in a fire compartment with small openings and the compartment geometry including openings and fire source location, and to discuss whether this combustion efficiency can be predicted from reduced-scale tests. The scale law on combustion efficiency was developed. Experiments were conducted using two compartments varying in linear size by a factor of 2 but geometrically similar in their over-all proportions. Different combustion efficiencies were observed due to the shape of opening and the place of fire source under the conditions with same ventilation factor. The measured combustion efficiencies in the two geometrically similar enclosures showed good agreement, which validated the scale law on combustion efficiency under the condition with 1.0 of equivalence ratio examined in this study.

　View Summary

A series of experiments are conducted for the establishment of the predictive method of the structural fire resistance of heavy hardwood (Zelkova), column normally used for traditional temple buildings. The experiments consist of(1) Measurement of the Young's modulus of Zelkova at elevated temperatures(2) Measurement of charring velocity and internal temperature of large size Zelkova column exposed to ISO834 Standard Time temperature curve.(3) Full scale tests for the validation of the predictive method of collapse time.The experiments reveal only minor difference of the mechanical and fire-resistive performance between Zelkova and conventional softwood. The validation test has resulted in the predictability of the structural fire resistance of Zelkova column at roughly 10% over-estimate.

FIRE AND MATERIALS 36 ( 5-6 ) 429 - 440 2012.08 [Refereed]

　View Summary

This paper describes group upward evacuation experiments using escalators that were designed to investigate the feasibility of evacuation by escalators for large underground buildings. The experiments were conducted using 22-m-high (50-m-long) and 5.7-m-high (12.2-m-long) escalators in a convention facility in Tokyo. In order to consider the potential benefits of using escalators moving towards an exit for evacuation, the experiments included both stationary and upward moving modes of the escalators. Walking behavior such as walking velocity and the effective flow coefficient was measured for solo walking pedestrians and groups in various arrangements. The influence of slow pedestrians (elderly, etc.) on the group evacuation was examined by using subjects wearing an elderly simulator (Instant Senior). The following conclusions were drawn with respect to the walking behavior on an escalator: (1) the walking velocity was nearly constant throughout the 22-m-high escalator lane, (2) the walking velocity of a solo pedestrian was 0.03-0.10m/s slower on a moving escalator than on a stationary escalator, (3) group evacuation on an escalator was strongly affected by the existence of slow pedestrians, (4) the walking velocity of a solo pedestrian on a stationary escalator was nearly identical to that on a stairway, and (5) the effective flow coefficient at the escalator entrance was dictated by the moving velocity of pedestrians on the escalator lane. Numerical evacuation simulations on a real and very deep subway station using the experimental results demonstrate a 46% reduction in the evacuation time by the use of escalators moving toward exits.

　View Summary

8 designs of traditional style bare timber eaves reinforced with conventional building materials to block penetration of an external fire into the building are proposed for the restoration and renovation of historic townhouses in Kyoto. The full scale fire resistance tests on the integrity and the thermal insulation of these designs against external fires revealed that these designs should be rated as either Fire Protective Construction or 45-60min Quasi-fireproof Construction.

　View Summary

The clay wall, unapproved as a fire-protective material in Building Standard Low, has a problem of the building confirmation. Therefore, clay wall is required to be analyzed on its fire-protective performance. Since clay contains a certain amount of organic substances, it has a probability of combustion and heat releasing. This paper reports the fireprotective ability of wall clay, examining through the cone calorimeter and the gas toxicity, utilized as a means of the approval tests for fireprotective material have been carried out. As a result, the wall clay, even enriched straw, proved that it has a performance of noncombustible matter.

　View Summary

Fire resistance tests are conducted on small-scale specimens of wooden wall with different positions and thicknesses of rockwool insulation in the wall. The tests have revealed significant influence that position and thickness of insulation in the wall give to the fire protecting performance of the wooden wall. It has been also clarified that putting insulation between wooden posts does not always make mechanical fire resistance improve, because positional relation between wooden post and insulated layer changed thermal distribution in the wall and damage wooden post given.

　View Summary

Response of pedestrians to the sudden stopping and restarting of an escalator is tested for the safe operation of escalators for evacuation in emergency in view of the recent significant popularization of escalators in underground facilities and traffic buildings. Two series of experiments are conducted, one with solo pedestrian on an escalator and another with a group of 12 pedestrians. The principal experimental parameters are upward and downward operations, time to and from steady-state velocity (current standard and slower), loading conditions(bags, baby). The pedestrians' responses are indicated by the visual observation of the pedestrians and by the questionnaires just after each test. The result of the experiments suggests general acceptability of the stopping of escalator by the current standard operation only for still pedestrians with hand on the handrail. For pedestrians with bags on both hands or with a baby, the stopping and the restarting of escalator should be slowed down to achieve safety equivalent with the stopping by the current standard operation for pedestrians with hand on the handrail. The tests also indicate fear of a pedestrian notably larger in a crowd than in a solo waling condition.

FEASIBILITY OF UPWARD EVACUATION BY ESCALATOR - AN EXPERIMENTAL STUDY

OKADA Naoko, HASEMI Yuji, MORIYAMA Shuji, OKAMOTO Emi

J. Environ. Eng. 76 ( 668 ) 855 - 862 2011

　View Summary

A series of on-site experiments are conducted on the upward evacuation by escalator of groups of 50 subjects including 12 simulated aged people. Two escalators, 49.5m long and 22m tall one, and 12.3m long and 5.7m tall one with parallel stairs in a large convention facility in downtown Tokyo, were used. The experiments revealed the following.1. Upward walking velocity on a still escalator, 0.78-0.79m/s for normal subjects, is nearly identical with that on normal stairs.2. Upward walking velocity on an escalator running at 0.50m/s is reduced by 5-10% from that on a still escalator.3. Upward walking velocity is virtually independent from the distance from the entrance within the range of 22m in height for normal and simulated aged pedestrians in spite of the height and length of each step significantly larger than those of stairs.4. Effective flow coefficient at the entrance is around 1.15 persons/ms for a still escalator and 1.78p/ms for a one running at 0.50m/s.5. The effective flow coefficient at the entrance of an escalator is reduced by the increase of the escalator length for the local congestions generally seen in long escalators.

Numerical reproduction of the sen'nichi department store fire and its damage factor analysis based on FSE evacuation safety verification method

Takuya Saito, Yuji Hasemi, Atsuyuki Ida, Koichi Naruse

AIJ Journal of Technology and Design 16 ( 33 ) 553 - 556 2010.06

　View Summary

The Sen'nichi Department-store fire(1972, 118 victims) is noted for the largest loss of life in a single building fire. This work intends to reproduce numerically the smoke spread and evacuation during the fire, and further applies the numerical simulations to inspect the validities of then-discussed assumptions and speculations for the largeness of the life loss and for the possible improvement of the fire safety. The study suggests any better crisis management could have reduced the number of victims but the failure of the smoke separation through elevator shaft, staircases and ventilation duct was the essential cause for the life loss.

　View Summary

Predictive method of the fire resistance of Japanese traditional bare-timber soil wall construction is proposed assuming its general dependence to the buckling of the posts due to the eccentric reduction of the post section by charring and the reduction of the Young's modulus of wood at high temperature. The constraint coefficient in the Euler's buckling formula has been determined for this construction according to post compression tests using post specimens engraved to reproduce the mechanical performance after design fire exposure times. The validity of this method has been verified against a series of wall furnace tests using one-story tall wall specimens.

日本建築学会環境系論文集 72 ( 611 ) 1 - 6 2007.01

　View Summary

As a comprehensive system of natural ventilation and smoke control for atrium buildings, an atrium building with a solar chimney is proposed In this building, natural ventilation is acquired with stack effect prompted by solar energy collection at the chimney. In case of a fire, the escape route is secured from smoke by keeping the neutral pressure plane in the chimney and the pressure of the atrium lower than outside. In this paper, the design policy of the passive smoke insulation is promoted and that condition is studied by experiments and calculations. Major results are as follows 1. The possibility of passive smoke insulation of the escape shaft is confirmed through the model experiment and this method could provide the safety space for handicapped person for evacuation or fire fighters. 2. The condition for passive smoke insulation could be predicted by a single zone calculation and two-layers model. 3 For passive smoke insulation, openings between atrium and escape shaft (joint gap of doors and openings for ventilation) have to be smaller than certain ratio in addition to keeping the neutral pressure plane in the chimney.

Integrity of bare timber eaves characterizing Kyoto-style traditional townhouses against external fires is examined by experiments using different design details for "Mendo" board, the joint between the beam and the roof. The experiments show significant improvement of the integrity by the use of plaster or soil on either side of the "Mendo" board, or by increasing the thickness of the "Mendo" board. Although the bare timber eaves has been long considered the main drawback of the Kyoto-style townhouses with regard to fire safety, the study has revealed that code-acceptable integrity can be achieved without introducing any industrial fire retardant agents.

WT Ding, YJ Hasemi, T Yamada

ENERGY AND BUILDINGS 37 ( 4 ) 411 - 418 2005.04 [Refereed]

　View Summary

Double-skin facade is getting more and more attention as it provides many possibilities for energy conservation and at the same time creates good indoor environment. In this paper, natural ventilation performance of a double-skin facade is highlighted. A prototype building is proposed, which is thought to be an eight-storey office building with an atrium space in the north side. The south facade of the building is a double-skin facade and a thermal storage space called solar chimney is considered above the double-skin space. Actually, the double-skin space is connected with the chimney channel. Reduced scale model experiments and computational fluid dynamics (CFD) analysis are carried out in this research to evaluate the natural ventilation performance of the prototype building.

　View Summary

A series of experiments to study merged flame from Multiple fire Sources was carried Out. The porous 15-cm(2) burner was used as a unit burner and propane was employed as a fuel. Many burners with Various heat release rates were placed in a square configuration with various separation distances. Flame height was measured using video images and temperature distribution with height was measured using thermocouples. The numerical results from the Fire Dynamics Simulator (FDS) of the National Institute of Standards and Technology was compared with the experimental data, and the comparison results show that FDS correctly simulates the merged flame from multiple fire sources. In addition, an empirical model to estimate the merged flame height was developed considering the effect of separation distance. The validity of this model was confirmed from the comparison with the simulation results, and excellent agreement is found between the calculated merged flame height from the model and the numerical ones. To study the detailed structure of merged flame, 3x3 fire source configuration was taken as an example to quantitatively show oxygen mass fraction profiles and velocity fields, which were also given to indicate the formation mechanism of the merged flame.

　View Summary

The possibility of using the same system for natural ventilation and smoke control is examined. As an example, a prototype building is proposed. The proposed prototype is an eight-storey building with a solar chimney on top of the atrium. Reduced scale model experiments and Computational fluid dynamics analysis are conducted. As a result, when the area ratio of outlet to inlet is greater than 2, air change rate of the utility space reaches over 2 times per hour and in an event of a fire breaking out in the atrium, the neutral pressure plane of the smoke layer stays inside the chimney. Smoke infiltration into adjacent spaces used for evacuation is prevented. (C) 2004 Elsevier Ltd. All rights reserved.

　View Summary

As reported in previous paper, the compatibility of natural ventilation and smoke control in the prototype building has been confirmed. Based on the results, in this paper, CFD simulation is used to predict the detail performance of the natural ventilation system. At the same time, the smoke control function is confirmed. According to the prediction, following results can be obtained: When the area ratio of outlet and inlet is greater than 2, natural ventilation rate increases hardly, while as higher as the chimney is, the natural ventilation rate is. In summer since solar altitude is relatively high in Tokyo, the vertical solar radiation-collecting wall cannot get enough solar radiation, which leads the natural ventilation rate around summer decreases. To obtain stable ventilation rate throughout the year, performance improved type is proposed with inclining the mainly solar radiation-collecting wall. Comparing Tokyo with London, because the latitude of London is higher than Tokyo, the vertical solar radiation-collecting wall can get more solar radiation and stable ventilation rate throughout the year can be obtained in prototype as it is. In addition, the effect of wind on ventilation performance is analyzed. When outside velocity is lower than 1m/s, stack ventilation is dominant, when outside velocity is greater than 2m/s, wind ventilation becomes prevailing. To obtain stable ventilation rate, it is important to grasp the wind information of the region and properly arrange the inlets and outlets.

　View Summary

Recently natural ventilation promoted by stack effect is widely adopted for reducing energy consumption and obtaining good indoor environment. But from the view of fire safety, stack effect will easily make smoke spread to upper part of building. In this paper, the compatibility of natural ventilation and smoke control is studied through an atrium building. A prototype atrium building is proposed, whose natural ventilation effectiveness is firstly evaluated and then fire safety is examined. Numerical predictions are presented and compared with the experimental data performed on a scaled-down model. The results of experiments and CFD analysis show that solar chimney is quite effective on promoting natural ventilation. As to the examination of smoke control, with the increasing of outlet area, the neutral plane of the smoke layer rises to be inside the chimney. It is the desirable conditions, under which even if the smoke layer descends to below chimney, since it is under minus pressure conditions compared with outside pressure, smoke won't propagate to evacuation route. Passive smoke prevention of the prototype building is verified.

Fire resistance tests are conducted on small-scale specimens of wood/soil wall assembly with different construction details as a basis for developing code-acceptable traditional wooden constructions. The tests have revealed significant influence of both-side plastering of soil wall, thickness and water content of the soil layer and various reinforcements of timber/soil layer interface on the prevention of the heat and flame penetration through a wood/soil wall. lt has been also clarified that charring of the timber element, a major cause for the collapse of the wall due to fire, can be reduced by the protection of the load-bearing timber elements by soil or wood or by design considerations reducing fire exposure of the timber element.

Fire of an approximately 1,000m^2 wooden gymnasium is investigated with the interest in the verification of the fire safety design for heavy timber construction based on the insulation effect of char layer and in the mechanism of the fast fire spread from the activation of fire alarm to flashover. The conventional char layer growing velocity, 0.6mm/min, is supported from investigation of the remaining components. The fast fire spread is attributed to the full burning of the partition wall.

Heat flux and temperature measurement is carried out on a 2.5m tall 0.15m square steel column exposed to a 0.50 m square porous propane burner. Heat release rate and distance between the column and the burner has been changed systematically. Temperature rise on directly heated surface of the column is found to be restricted due to the conduction through the specimen. Flame heat flux on a steel column adjacent to the wall is represented as a function of height normalized by flame length, while distance between the fire source and the column has a significant influence on the incident heat flux on the steel column. Heat flux at the lower region of the flame is found to be lower than that for in wall flames probably due to the entrainment of ambient air to the flame passing around the column.

　View Summary

A prototype atrium building is suggested with a large solar chimney on top of the atrium, which is expected to promote natural smoke exhaust and accumulate smoke at a event of a fire and promote natural ventilation when outdoor climate is desirable. In this paper natural ventilation efficiency is evaluated. The solar chimney is similar to conventional chimneys except the south-facing wall is replaced by a glazing. Solar radiation transmits the glass and thermal energy is stored in the other three walls. Air in the chimney is heated and by stack effect natural ventilation is realized. Experiment is conducted on a 1/25 scale model to evaluate the efficiency of this solar assisted natural ventilation system. Several area conditions of inlet and outlet are chosen while other conditions keep the same. CFD simulation is simultaneously done. According to results of model experiment and simulation, natural ventilation promoted by the solar chimney is quite sufficient to meet the demands of atrium ventilation As to the office rooms, if area is properly set, fresh air requirement can be satisfied only by natural ventilation. In the case of this study, when inlet area changes to 24m2, necessary ventilation rate can be obtained. © 2002, Architectural Institute of Japan. All rights reserved.

Himeji-jo Castle is visited by numerous sightseeners every year. In order to derive fire safety measures for the visitors' safety, 1/25 scale model experiments were carried out to characterize the smoke movement in the castle's main tower. The experiments demonstrate interesting effects of the architectural features of the castle to the smoke movement. The tests generated detailed information on the distribution of smoke for different fire scenarios ; zones left safe and others invaded by smoke. Integration of these results with the evacuation characteristics of the building should be essential for the func- tional life safety planning of the castle.

　View Summary

The limit for the measurement of moisture content of wooden members has been expanded to the extent that changes in moisture content could be traced from air-drying conditions at ambient temperature to the end of standard fire-resistance test. Thermal conductivity of wood at high temperature at different fiber directions was measured for the development of heat/moisture transfer model, resulting in the extremely strong anisotropy in the fiber directions; it strongly suggests that the transfer of water in axial direction of a wooden load bearing member can affect its mechanical performance. From these results, several mysteries in the fire behavior of wood such as the fact that the relationship between the deformation and span of wooden beams during a fire tends to be different from that of steel or concrete, and the inconsistency between the charring rate and the mechanical performance of wood during fire heating have been found to be caused by moisture transfer due to fire heating.

It is important to comprehend ‘solar dependence' (proportion of energy consumption of the building that can be covered with solar energy) adequately in the solar energy use building. This research was contrived the energy balance sensor robot system of the building which evaluate in real time in the building under operation and conducted the basic experiment operation method about the solar dependence evaluation system. The energy balance sensor robot system of the building was considered about the whole composition and function. Both the technique for setting the heat flow sensor at key point in interior decoration material and the emulator technique for using thermally analogous models were contrived. As a technique of the former, solid state properties of interior decoration material was assembled and suitable member for the sensor was selected. On the one hand, observational study of inner wall temperature of the building under air conditioning was conducted. As a result, inner wall temperature distribution and actual conditions of energy consumption was clarified. As a technique of the latter, the theory of the emulator that was able to evaluate the skin load in the building in real time was constructed. And the basic experiment was conduct in order to verify the theory. The emulator understands the skin load in an actual building from the skin load of the thermally analogous model in the building. The emulator differs from method of measurement with a lot of sensors and method of measuring outdoor conditions with meteorological observation equipment and calculating skin load. The basic experiment that used three thermally analogous models was conducted under various conditions. As a result, the correctness of the emulator was able to be verified

　View Summary

Improvements in the safety performance of city blocks of traditional wooden housed area cannot solely rely on either measures within urban planning or control over individual buildings by the building code. When the safety performance of individual buildings cannot be secured, urban planning measures should cover the insufficiency; when urban planning measures themselves are insufficient, measures for individual buildings should also be considered. In this mutually supplemental fashion, the local characteristics of a city block can be maximized and the measures can work more effectively. This study aims to evaluate the comprehensive safety performance of an entire block, going beyond the safety performance of individual buildings. Though simulation of the spreading of a fire is the primary evaluation system for the safety of a block, it was difficult to analyze the simulated results and work out measures to be taken by running merely a single simulation. Therefore, evaluation of safety performance in this study is based on potential risks. Fire risk can be assessed by block as well as by building in the same method. The safety index by building as obtained here thus reflects not only the performance of the building but also the influence of the block performance, which is obtainable through examination of the positional relationship of buildings in the block and the condition of the surrounding buildings, enabling the building performance at the block level to be indicated. This evaluation method allows the potential risk of the block to be clearly recognized, and the effectiveness of plans for improvement can be well understood through this evaluation with a simulation of the plans in practice

　View Summary

For the purpose of energy conservation and requirements for improving indoor air quality, buildings employing natural ventilation are increasing recently, among which the planning of utilizing atria or vertical shafts to promote stack ventilation is not scarce. In conventional researches, 'Sterile tube' solution has frequently been used, but due to the many restrictions on the atrium design and the use of the building/atrium, it is always not favored by designers. As for the other solutions, such as using a great number of shutters to separate adjacent spaces from the atrium, besides high initial cost, it is difficult to ensure that all shutters work properly, because they are only used in case of emergency and if only one of those shutters fails to close, evacuation behavior may be delayed or fail. Proper smoke control method is urgent to be found out. In this thesis, the possibility of using the same system both for natural ventilation and smoke control is examined.To secure fire safety of a building with natural ventilation planning, a new smoke control method is proposed in this research. As the prototype building, the space of the solar chimney can be used to promote natural ventilation by absorbing solar radiation, and at the same time making the neutral plane stay in the chimney, smoke prevention can be realized by pressure difference. This concept is confirmed by reduced scale model experiments and CFD calculation

高齢者擬似体験用具を使用した高齢者の避難行動特性の定量化の手法

　View Summary

高齢者擬似体験用具を装着した健常者(以下「擬似高齢者」と称す)による高齢者の歩行行動の再現可能性を検証するため、同様の実験条件において、実際の高齢者と擬似高齢者双方(以下「擬似高齢者等」と称す)による実験を行った。まず擬似高齢者等の単独での歩行行動を実測することで歩行行動の特性を把握し、次に擬似高齢者等と健常者が混在する群集について、擬似高齢者等の人数と配置を変化させて歩行速度を実測し、擬似高齢者等の存在が群集全体の歩行行動特性に及ぼす影響を分析した。その結果、以下の事項が明らかとなった。(1)高齢者擬似体験用具は、水平歩行時には視聴覚装備より手足の束縛や杖の使用が歩行速度に与える影響の方が大きい。(2)水平歩行の場合、擬似高齢者は単独歩行時と群集歩行時の歩行速度の差が大きく、群集歩行時には歩行速度が斉一化するが、実際の高齢者は水平歩行時の単独時歩行速度と群集時歩行速度の差が小さい。擬似高齢者は階段歩行時には単独時歩行速度と群集時歩行速度の差が小さくなり、水平歩行時に比べ高齢者の歩行行動をより良く再現する。(3)実際の高齢者は同じ年齢層でも歩行速度の個人差が大きく、系統的なデータを得るのは困難であるが、擬似高齢者の歩行速度は群集歩行時0.7〜1.1m/sの範囲に収斂し、この値は実際の高齢被験者の中でも年齢が高く歩行速度が遅い被験者の歩行速度に相当するため、擬似高齢者は高齢者の代用になり得る。(4)群集後方の健常者が前方の擬似高齢者を追い越して歩行できる場合、群集密度が約2.6人/m^2以下であれば群集は軽交通の歩行状態となり、歩行速度が約0.8m/sの擬似高齢者が群集内に1人増加するに従って群集全体の歩行速度は約0.1m/s低下する。擬似高齢者が群集前方に集中的に配置される場合、後方の健常者は前に出られず群集は重交通の歩行状態となり、密度が約1.9人/m^2以下でないと歩行状態は安定しない
局部火災加熱を受ける金属柱の力学的応答とその予測

　View Summary

既往の研究により、局部火災時の柱部材の温度分布までは火源条件が与えられれば予測が可能となっており、次の段階として、温度分布から部材の力学的挙動を予測し、架構の安全性を評価することが目標となる。まず、力学的応答予測に用いる有限要素法などの数値解析の検討モデルたり得る実験データを得ることを念頭に、局部火災加熱を受ける鉄骨角柱の載荷実験を行い、その挙動を把握した。実験は拘束条件や加力条件を変えて4種行われ、水平変形形状の推移、柱頭での熱応力拘束力、鉛直変位の推移などを把握した。さらに、これら実験結果をもとに力学的挙動予測のための有限要素モデルの確立を目的とし、上記の各実験と同じ条件で柱の挙動を有限要素法にて再現することで、熱膨張率や材料特性の設定、解析方法などを検討した。解析は汎用有限要素法ソフト"ANSYS"を用い、実験で計測された温度分布をモデルへの入力条件とし、実験ごとの拘束条件にて構造解析を行った。解析では、熱膨張率の温度依存性を設定し、鋼材の温度ごとの強度を引っ張り試験を基に多直線で近似した。その結果、試験体温度分布がある程度定常状態に近付いた後の鉛直方向の拘束力ならびに鉛直変位に関しては高い精度での予測が可能であることを示した。さらに座屈荷重を求める解析では、初期不整を求める事前解析において、温度上昇に伴う鋼材強度の低下をヤング率の低減に置き換える方法を示した。局部座屈が生じた後の挙動に差があるものの、局部座屈発生時の軸力値はよく一致し、誤差は10%以内であった

大断面木質部材の防耐火性能設計の工学モデル

2012

　View Summary

鋼材等の構造材料に比べて防耐火性能の工学的予測が著しく立ち遅れている木材について、火災加熱時の部材断面の力学的性能を予測する基礎情報として、以下の実験研究を行った。火災加熱を想定した高温下での熱分解・燃焼性状の温度帯別測定スギ・カラマツ・ベイマツ・アカマツ・キリ・ケヤキの無処理材及びスギ難燃処理材について、400℃以下の範囲で温度帯別に吸熱・発熱特性を空気及び窒素雰囲気中で測定した。木材の力学的物性に対する温度上昇の影響の把握構造用木材であるスギ、カラマツ、ベイマツ、ケヤキについて、炭化に至らない200℃以下の範囲で、高温時及び高温から常温に低下した段階でのヤング係数及び曲げ強度を測定した。
病院病棟の管理実態にもとづく災害時人命安全計画

2007

　View Summary

病院病棟は、診療科によっては自力避難できない患者が数多く存在し、火災等の災害時に人命危険が及ぶ前に避難完了させるには病院職員の介助を前提とする避難を機能的に行う必要がある。しかし、病棟の避難で一般に想定されるストレッチャー等を用いた担送避難等については病室での担送器具への移動、避難先での担送器具からの移動等を含む避難時間の予測自体に困難があり、介助避難を合理的に計画する基盤は脆弱であった。本研究では、ストレッチャー、シーツ、車椅子を使用した介助避難を想定して、病因病等で多数の患者が同時に避難する状況を反映させた避難行動実験を、実際の病院病棟階において改装のため不使用となる期間を利用して実施し、それをもとに病院病棟における群集介助避難時間を予測するモデルを作成した。更に、本モデルに基づいて、病院病棟の平面計画と夜間管理体制が、病棟における群集避難時間にどう影響するかを明らかにし、病院病棟の防災計画やその評価の基盤となる手法として提案した。　一方、本研究では、神経内科、小児科等では自力避難できない患者比率が極めて高く、この防災計画手法では、日常的な医療行為と合理的な避難計画を両立させるのは極めて困難であるとの見通しが得られた。そこで、火災時でも出火室以外の病室は避難しなくても在室患者の人命安全を維持できる「災害時避難不要病棟」の概念を考案して、その技術的可能性を検討した。それには出火室の排煙・共用廊下の加圧、出火室間仕切りを通じる延焼防止が必要であるが、病室では火災荷重が小さく、他室との間の区画性も高いことから、火災継続時間は短く、壁を介する延焼防止は容易であること、居室の必要排煙量は一般的な排煙と特に変わらないこと等を明らかにし、避難不要病棟とする上で特に検討が必要なのは共用部分の加圧を確実にするための平面計画と、遮煙性を確保できる病室扉の開発のみであり、技術的実現可能性が高いことを明らかにした。
自力避難困難者の多い施設の避難安全計画に関する基礎的研究

2006

　View Summary

高齢化に伴う高齢者施設の増加、バリアフリー化の進行に伴う公共施設の障がい者・高齢者の利用の増加等を背景として、災害時に自力避難できない在館者の多い施設が増加している。一方、火災時の人命安全は一般的には地上までの避難を前提としているが、こうした自力避難困難者の増加を防災的にどう補って人命安全性を確保するかは調査研究のレベルでも立ち遅れており、2005年頃からは高齢者施設等を中心に複数の死者を出す火災が発生し始めている。高齢化の更なる進行によって高齢者施設が増加すれば、その火災被害が大規模化したり、死亡火災が頻発化することが予想されている。本研究は、高齢者福祉施設を中心に、自力避難困難者の居住実態と施設の防災管理体制を調査し、併せて、高齢者の行動能力を避難計画という観点から実測調査するものである。本研究では、2000年以降、増加してきた認知症グループホームについて、東京都内の施設の悉皆調査を行い、多くの施設において、出火後早い段階で確実に消火・介助避難するための設備・管理体制が成立していないこと、居住者の要介護度は居住年数とともに進行し、避難上の困難が増加する傾向があること等を明らかにした。また、東京都の高齢者住宅(シルバーピア)で発生した火災の記録の悉皆調査を行い、高齢者住宅でも、認知症等の症状を伴わない場合は、生活様態によっては出火率が一般世帯よりもむしろ低下し得ること、出火後、早い段階で駆けつけることができる人がいることが高齢者施設の人命安全の向上に極めて効果的であること等を明らかにした。一方、高齢者・障がい者の避難行動特性の実験的把握は、被験者確保の容易性のため、健常者に擬似高齢者体験用具を装着させて実施するのが通例であるが、実際の高齢者の行動能力を再現し得ているかについては疑問があった。本研究では、高齢者住宅の住民の協力を得て、実際の高齢者、車椅子使用者の歩行行動能力測定を実施し、擬似高齢者体験用具による実験方法の指針を誘導した。
歴史的都市景観保存と両立する地域防災対策手法

1997

　View Summary

全国の重要伝統的建造物群保存地区(伝建地区)のうち市街地を構成する28地区を対象としてアンケートによる防災意識及び防災安全性の実態を把握するための調査を行った。この結果から、都市内に存在する伝建地区では空家の増加と定住人口率の低さが地域防災の課題を特徴づけているのに対して、小都市や集落型の地区では高齢者人口比率の増加が顕著であること、更に、これらの課題に対する地域共同体の取組は、小都市・集落型の方が大都市型伝建地区より総じて積極的であることなどが判明した。また、土蔵・塗屋系の町家は防火性能は高い反面、街路等に対して住宅が閉鎖的であるため、近隣関係が疎遠になる傾向があり、地域災害における近隣の協力関係の形成をかえって阻害する傾向があることが判明した。　研究代表者が地域防災計画を指導・支援している岐阜県高山市三町伝建地区を対象として、歴史的景観に影響しない地域防災対策手法として防火塗料とケーブルネットワークの適用性のケーススタディを行った。即ち、木造軸組工法の伝統的町家群の出火・延焼抑制手法として、透明性の高い防火塗料を試作し、施工直後での防火性能の確認と促進暴露試験による耐候性の把握を行ったうえ、岐阜県高山市三町伝建地区の修景建造物に適用して、この手法の景観への影響評価と今後の防火性能の経年変化の検討を進める基盤を整えた。既に防火を目的として敷設が始まっているケーブルネットワークについては、利用者の満足度等を生活実態と併せて調査し、今後、住民の急病・事故等の際の通報機能等を付加すれば、本地区が直面する種々の地域安全上の課題の解決に著しく寄与し得ることが判明した。研究成果の発表1998年5月　日本火災学会研究発表会「重要伝統的建造物群保存地区における地域防災の基盤的条件について」1999年7月　The Sixth International Symposium on Fire Safety Science(投稿中)“A Regional Fire Safely Planning for Wooden Preserved Historic District”
