To prevent the function of a bearing wall from deteriorating even when a large external force repeatedly acts on a wooden framework structure, an end face of a brace from being damaged even when a large force acts on the bearing wall from multiple directions, a brace itself from buckling or breaking, and the brace from being embedded in a horizontal member.SOLUTION: A brace bearing wall 1 of a building of a wooden framework structure formed by mounting a brace 6 on a diagonal line of a rectangular frame made up of right and left columns 2, 3, an upper side horizontal member 4 and a lower side horizontal member 5 is configured such that at an upper corner part of the rectangular frame to which the brace 6 is attached, an upper end surface of the brace 6 and a lower surface of the upper side horizontal member 4 make surface contact with each other; at a lower corner portion of the rectangular frame to which the brace 6 is attached, a lower end surface of the brace 6 and an upper surface of the lower horizontal member 5 make surface contact with each other; and an upper end 6B and/or a lower end 6C of the brace 6 are made of a first low elastic modulus member having a lower longitudinal elastic modulus than that of the upper horizontal member 4 or the lower horizontal member 5.SELECTED DRAWING: Figure 1
【課題】木造軸組構造に大きな外力が繰り返し作用しても、耐力壁の機能を低下させることなく、耐力壁に大きな力が多方向から作用しても筋かい端面が破損したり、筋かい自体が座屈したりや破断することなく、筋かいが横架材にめり込むのを防止する。【解決手段】左右の柱２、３、上側横架材４及び下側横架材５で形成される矩形の枠の対角線上に筋かい６を取り付けて形成される木造軸組構造の建築物の筋かい耐力壁１において、筋かい６が取り付けられる矩形の枠の上側の隅角部において、筋かい６の上端面と上側横架材４の下面が面接触し、筋かい６が取り付けられる矩形の枠の下側の隅角部において、筋かい６の下端面と下側横架材５の上面が面接触し、筋かい６の上端部６Ｂ及び又は下端部６Ｃを、上側横架材４又は下側横架材５より縦弾性係数が小さい第１の低弾性係数部材で構成した筋かい耐力壁１。【選択図】図１
