     View Summary

    <p>In Japan, the cob construction is often used for fences, but is rarely used for buildings. These buildings are being dismantled by aging and change of owner. We conducted measurement on the warehouse and the wall built with the cob construction method around the Yamanobe road in Nara prefecture. As a result, it is found that there is relationship between the structure of the warehouse, the area and the application. Furthermore, it was possible to estimate the construction method from the states of the mud wall.</p>

  • THE INFLUENCE OF THE BEHAVIORS OF LAYERS UPON THEIR MECHANICAL CHARACTERISTICS AND FRACTURE BEHAVIORS:Wall clays for clay wall on bamboo lathing Part4

    Journal of Structural and Construction Engineering (Transactions of AIJ)   82 ( 734 ) 503 - 512  2017  [Refereed]

     View Summary

    &nbsp;Clay wall on bamboo lathing is a traditional Japanese method of constructing walls using a timber framework, bamboo lathing, and plaster produced by mixing clay and straw. Although the use of clay walls is environmentally friendly, it is necessary to evaluate the performance of the walls, especially their structural resistance, so that they can be used widely and safely.<br>&nbsp;This paper aims to clarify the influence of the behaviors of plastering layers of clay walls upon their mechanical characteristics and fracture behaviors. Two experiments were conducted, that included diagonal loading onto small element specimens, referred to element experiments, and the loading of horizontal force onto structural specimens, referred to structural experiments.<br>&nbsp;First, the element experiments were conducted to clarify the influence on the mechanical properties of three factors; (1) degree of looseness around the end of &ldquo;bamboo furring&rdquo;, that is inserted into holes in the sides of neighboring framework members, (2) composition of wall clay mixture for each plastering layers, base-coat layer and middle-coat layer, and (3) ratios of thickness between the base-coat and middle-coat layer. As a result, we clarified the followings;<br>&nbsp;(1) In case of without looseness around bamboo furring, the load tends to small because larger delamination between the face and back of the base-coat layer is created.<br>&nbsp;(2) The initial stiffness was high with the specimens using mixture had large elastic modulus and compressive strength for the middle-coat layer, so that this layer started to resist at an early stage of loading. Then around the maximum load point, after the corners of the base-coat layer started to resist, the load was large with the specimens using mixture had large absorbed energy for the base-coat layer.<br>&nbsp;(3) The initial stiffness was higher when the middle-coat layer was thicker, so that this layer started to resist at an early stage of loading.<br>&nbsp;Secondly, the structural experiments were conducted to confirm the results of the element experiments. The specimens employed had the same cross-sectional dimensions of framework members as those used in real buildings. However, the specimens were proportionally smaller in height. The specimens had different factors based on the result of element experiments. Horizontal force was loaded to the positive and negative sides, alternating every three cycles until the prescribed deformation angle was reached. As a result, we clarified the followings;<br>&nbsp;(1) From the observation of the destructions, we confirmed four elements contributed to resistance to the horizontal forces. These resistance elements exist different layers, two base-coat and two middle-coat layers. Therefore, resistance of those elements cause the different behaviors of each layers and cause the delamination at the interface of layers that are difficult to repair.<br>&nbsp;(2) Clay walls of high initial stiffness can be achieved by avoiding gaps around the resistance elements. However, such walls tend to develop the delamination at the interface of layers.

    Journal of Structural and Construction Engineering (Transactions of AIJ)   78 ( 689 ) 1209 - 1218  2013  [Refereed]

     View Summary

    The use of clay walls on bamboo lathing less burdens on the environment, but it is necessary to confirm their properties in order to use this wall construction method more widely in safety. In this paper, these properties are measured, including workability, crack and compression characteristics. Tests result in the followings conclusions. In the case of wall clay for the base coat layer, when fiber content increases, elastic modulus and compressive strength decreases, but the two layers across bamboo lathing become monolithic, and toughness is improving. In the case of the middle coat layer, to keep a high level of compression characteristics require minimum amount of straw to avoid cracking.

     View Summary

    The use of clay walls on bamboo lathing less burdens on the environment, but it is necessary to confirm their properties in order to use this wall construction method more widely in safety. In this paper, fracture behaviors were observed, including full section sized specimen and element specimen which were loaded force. As a result of full section sized experiments, four types of behaviors as load-bearing elements could be found. As a result of element experiments, when all four types of elements bearing the load compare with one element, the initial stiffness improved, but the toughness decreased because of the delamination at the interface of layers were markedly happen.

  • PROPERTIES OF WALL CLAYS USED IN REMAINING AND RESTORED MUD WALL STOREHOUSES, DOZOH, IN WAJIMA, NOTO

     View Summary

    This study revealed the fundamental properties of wall clays, which were used in two mud wall storehouses, Dozoh, in Wajima, Noto. These Dozoh were subjected to the destructive earthquake occurred in March 25, 2007.<br>Some of the test samples were taken away from a Dozoh which was constructed in the end of the Edo period and was seriously damaged by the earthquake. The other samples were newly excavated from the area around there and then one of them was used to repair the clay wall of the other Dozoh whose framework was slightly injured.<br>It was found that the particle size of the wall clay used for the restoration of the Dozoh was smaller and its compressive strength was greater than those of the clay used in the other ancient one.

  • 日本における土や石を用いた組積構法に関する研究

    2021  

     View Summary

    日本の建築構法としては珍しい土や石を積んだ壁を有する建築について、その実態把握と、構法、材料および施工方法の整理を目的とし、山口県および福岡県の建築を対象として聞取り調査および実測調査を行った。その結果、山口県・福岡県の土・石積み建築として、米の保管などに用いられる建築(①)や、農業用の堆肥や肥料の保管に用いられる建築があることがわかった。これらの建築の上部構造の支持方法、各部構法、土・石積み壁の材料および施工方法を整理した。①はいわゆる「土蔵」と外観・用途が同様であり、日本において木造軸組の小舞土壁構法以外にも「土蔵」の構法が存在すること、またその分布や構法を明らかにすることができた。

  • 小舞土壁の構造耐力を向上する塗付け各層の組み合わせおよび塗付け方法に関する研究

    2014  

     View Summary

     伝統土壁構法の構造耐力を向上するため、土壁を構成する塗付け層の組合せおよび塗付け方法の影響を検討した。土壁の抵抗要素を模擬した試験体のせん断加力実験を行なった。 その結果、塗付け各層の組合せによって、荒壁層の表裏のはく離が先行する場合と、荒壁層と中塗層の層間におけるはく離が先行する場合が確認でき、後者のほうが、荒壁層内部の損傷は少なく、大変形時まで荒壁層が粘り強く抵抗する傾向が明らかとなった。 また、荒壁土の塗付け方法は、間渡竹が荒壁層をこじることによる抵抗に影響を及ぼすことが明らかとなり、塗付け方法の改善によって荒壁層の抵抗力を向上できる可能性が示唆された。
