BEARING WALL WITH DIAGONAL MEMBER/DEFORMATION ABSORPTION DEVICE
PROBLEM TO BE SOLVED: To provide a bearing wall with a diagonal member/deformation absorption device in which steel usage can be reduced while being superior in energy absorption performance, also an opening portion can be provided without causing performance degradation and disadvantage in construction, and vertical frame member buckling properties caused by using different types of bearing elements can simply be prevented.SOLUTION: A bearing wall is partitioned in multiple partition layers a, b arranged vertically, and is provided with a bearing element in each partition layer. The bearing element of a part of the partition layer b comprises a pair of diagonal members 8 disposed in an inverted V-shape or V-shape to each other. A deformation absorption device 9 for absorbing deformation of the partition layer b is provided in mutual approach side edges of the pair of diagonal members 8. The deformation absorption device 9 comprises a pair of vertically parallel plates 22, a plate-like web 23 for absorption of energy, and upper and lower horizontal plates 24. The web 23 is inclined to the wall surface and the parallel plates 22.
【課題】 エネルギー吸収性能に優れながら、鋼材使用量が少なくて済み、また性能低下や施工上の不利を生じることなく開口部分を設けることができ、かつ異なる種類の耐力要素を用いることにより生じる縦フレーム材の腰折れ状の性状を簡易に防止することができる斜材・変形吸収デバイス付き耐力壁を提供する。【解決手段】 上下に並ぶ複数の区画層ａ，ｂに区画され、各区画層に耐力要素が設けられた耐力壁である。一部の区画層ｂの耐力要素が、互いに逆Ｖ字またはＶ字状に配置された一対の斜材８からなる。一対の斜材８の互いに近寄り側端に、区画層ｂの変形を吸収する変形吸収デバイス９を設ける。変形吸収デバイス９は、一対の縦姿勢の平行板部２２と、エネルギー吸収用の板状のウェブ部２３と、上下の水平板部２４とでなる。ウェブ部２３は、壁面および平行板部２２に対して傾斜している。【選択図】 図１
