摘要

It has been important to evaluate building's structural performance to wind action as much as earthquake. The aims of this study are to understand elasto-plastic wind response characteristics and propose elasto-plastic wind response analysis methods of detached timber-frameworked buildings. In this paper, at first, an analytical model of the building is shown, then wind force characteristics acting on small-scale and low-rise buildings and their simulation method are discussed. Next, pseudo-dynamic tests are carried out to timber-frameworked shear walls, then wind response characteristics obtained from the tests are described. Finally, analyses using the restoring force characteristics models that has been proposed by the authors are conducted and validities are considered by comparison with results of the pseudo-dynamic test.%建築基準法の改正等，建物の構造性能評価が重要視される傾向に ある。構造性能の検証・表示の具体的方法の一つとして挙げられる 限界耐力計算は，地震，風，積雪といった外力・荷重に対して構造 の要求性能を設定し，その性能を確認するものである。しかし風外 力など地震以外の外力に対する構造性能評価の情報は少ない。
