薄板軽量形鋼造建築物耐カ壁における単調載荷履歴特性の評価方法

摘要

阪神淡路大震災後にァメリ力から導入された薄板軽量形鋼造建築物は，2012年の告示改定により4階建てまで可能になり，需要がよ り一層高まることが期待される。%The bearing walls of steel framed houses behave complicated ways, because it is influenced by not only searing and bending deformation but also the behavior of drilling screws jointing plywood to studs. Nowadays, structural properties of the bearing walls have to be estimated by full-scale experiments to design a steel framed house. But in order to estimate those properties without experiments, it is needed to make clear sufficiently about the bearing mechanism of walls. In this paper, on the basis of studies on full-scale experiments made by authors, the simple method by which the characteristics of load-deflection relationship on steel-framed bearing walls can be easily estimated, will be discussed. By the comparison with experimental results, it is shown that the proposed method is effective.
