短い軸組材を使用した木造壁体の耐震改修性能評価 Evaluation of earthquake resistant improvement performance of wooden walls using short members 岩井, 哲 イワイ, サトシ 佐藤, 立美 サトウ, タツミ 坪山, 宗由 ツボヤマ, ムネヨシ Iwai, Satoshi Sato, Tatsumi Tsuboyama, Muneyoshi wooden frame earthquake resistant improvement static loading test wall unit multiplier hysteretic energy absorption failure property application/pdf This study aims to reuse timber building materials pulled down from an old existing house for earthquake-resistant improvement. Totally seven specimens, composed with four kinds of structural types, were used to subjected to static repeated load horizontally. The load carrying capacity, deformability, hysteretic energy absorption, and failure mode of the specimens were investigated. It is found that the specimens installed three sets of crossed short-diagonal members show the highest load-carrying capacity, those were about 2.0 of wall unit multiplier, which is equivalent to the wall with crossing braces of the same size cross-section. The hysteretic energy absorption quantities of these specimens were also large, comparing the other specimens. However, the members failed in splitting and brittle manner at the ultimate stage of loading, so there must be change in the failure mode. departmental bulletin paper 広島工業大学 2012-02 VoR application/pdf 広島工業大学紀要. 研究編 46 31 37 AA11599110 13469975 https://it-hiroshima.repo.nii.ac.jp/record/909/files/kenkyuhen46031.pdf https://it-hiroshima.repo.nii.ac.jp/records/909 jpn 40019182398
