REINFORCED CONCRETE STRUCTURAL WALL
PROBLEM TO BE SOLVED: To provide a reinforced concrete structural wall capable of controlling a crack generation position with easy management without using cross-section deficiency material which is embedded inside concrete.SOLUTION: In a reinforced concrete structural wall, at least a part of a plurality of transverse reinforcements 14 is arranged so as to have a transverse reinforcement right part 14R and a transverse reinforcement left part 14L dividedly formed in the length direction and so as to form a divided part in which the transverse reinforcement right part 14R and the transverse reinforcement left part 14L are separated in the length direction. A weak adherence section is set, which is the section between a position P1 separated from the left end of the transverse reinforcement right part 14R toward the right by an anchorage length (40d) and a position P2 separated from the right end of the transverse reinforcement left part 14L toward the left by the anchorage length (40d). Further, when crack control regions 18 are set as two regions which spread from respective left and right ends of a pair of inducing joints 15 to left and right at 45 degrees respectively in a plan view to the thickness direction of wall concrete 12, at least a part of the weak adherence section is arranged in an overlapping portion 18a of the two crack control regions 18.
【課題】コンクリート内部に埋め込む断面欠損材を用いることなく、かつ容易な管理でひび割れ発生位置を制御できる鉄筋コンクリート造構造壁を提供する。【解決手段】複数の横筋１４のうち少なくとも一部を、長さ方向に分割形成された横筋右部１４Ｒおよび横筋左部１４Ｌを有するとともに、横筋右部１４Ｒと横筋左部１４Ｌとが長さ方向に離間する分断部を形成するように配置し、横筋右部１４Ｒの左端から右方に定着長さ（４０ｄ）離れた位置Ｐ１と、横筋左部１４Ｌの右端から左方に定着長さ（４０ｄ）離れた位置Ｐ２との間を弱付着区間とし、１対の誘発目地１５のそれぞれの左右両端から壁コンクリート１２の厚さ方向に対して平面視で左右にそれぞれ４５度の角度で広がる２つの領域をそれぞれひび割れ制御領域１８としたときに、弱付着区間の少なくとも一部を２つのひび割れ制御領域１８の重畳部分１８ａに配置する。【選択図】図３
