PROBLEM TO BE SOLVED: To provide a design method for a reinforced concrete structure that widens a living space.SOLUTION: A position of a column 3, for which a yielding hinge Q is planned, is set at a boundary part between a high strength portion 311 and a normal strength portion 312, at a location away from a root part R of a column base part 10A that is a column-beam junction part 10. When a reinforced concrete structure is exposed to large force, deformations concentrate at the boundary part between the high strength portion 311 and the normal strength portion 312, instead of the root part R of the column base part 10A. As such, the configuration keeps an amount of reinforcement small, does not require increasing of a cross-section of a beam or the column-beam junction part, and therefore widens a living space.SELECTED DRAWING: Figure 3 |
