薄板軽量形鋼造建築物耐力壁の力学的特性に関する実験的研究: ドリルねじピッチと縦横比が与える影響

摘要

阪神淡路大震災後にァメリカから導入された薄板軽量形鋼造建築物(スチールハウス)は、わが国独自の鋼材俱楽部規格の薄板軽量形鋼や告示1641号(2001年)の制定によって普及、さらに2012年の告示改訂によって4階建てや併用構造も可能になり、スチールハウスの需要はより一層高まることが予測される。%The bearing walls of steel framed houses behave complicated ways, because it is influenced by not only the properties of plywood and also the behavior of drilling screws jointing plywood to studs and another. So, nowadays, structural properties of the bearing walls are estimated by full-scale experiments to design frames. 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, we cany out full-scale experiments, paying attention to two factors-pitch of drilling screws and height-width ratio of the bearing wall-, and discuss the influence of those factors to structural properties of the bearing walls.
