DESIGN METHOD FOR REINFORCED CONCRETE STRUCTURE, AND REINFORCED CONCRETE STRUCTURE
PROBLEM TO BE SOLVED: To provide a design method for a reinforced concrete structure that is less prone to development of a crack or other forms of fracture toward a beam center side, from a setting position of a yielding hinge.SOLUTION: A region 21M on a junction side positioned on a cruciform junction S1 is set as a first high strength portion 211A of a main reinforcing bar 21 of a beam, while a region 21N on a beam center side positioned on an opposite side of the cruciform junction S1, with a normal strength portion 212 in between, is set as a second high strength portion 211B. For calculating an amount of reinforcement of the main reinforcing bar 21 assuming bending moment at a position Q of a yielding hinge as design bending moment, the position Q of the yielding hinge is set at a boundary part between the region 21M on the junction side and the normal strength portion 212.SELECTED DRAWING: Figure 2
【課題】降伏ヒンジの設定位置から梁中央側に向かってひび割れ等の破壊が進行することが少ない鉄筋コンクリート造の設計方法を提供する。【解決手段】梁用の主筋２１の第一高強度部分２１１Ａを、十字形接合Ｓ１に位置する接合部側領域２１Ｍとし、第二高強度部分２１１Ｂを、普通強度部分２１２を挟んで十字形接合Ｓ１とは反対側に位置する梁中央側領域２１Ｎとし、主筋２１の鉄筋量を、降伏ヒンジの位置Ｑの曲げモーメントを設計用曲げモーメントとして算定するにあたり、降伏ヒンジの位置Ｑを接合部側領域２１Ｍと普通強度部分２１２との境界部に設定した。【選択図】図２
