摘要
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
