PROBLEM TO BE SOLVED: To improve work easiness, while efficiently arranging a reinforcing material, and securing its deforming performance in a big earthquake, even if a cross section of a concrete member is large. SOLUTION: This concrete member (a concrete pier 1) has an optional cross-sectional shape of arranging an axial reinforcement 20. The reinforcing material (a first restraining reinforcement 3) partially restrains the compression edge of inside concrete 1b on the inside of the axial reinforcement 20, and is arranged in a plurality along the compression edge in a plastic hinge section 1a formed when external force acts on this concrete member. The whole inside concrete 1b can be efficiently restrained by restraining the compression edge of the inside concrete 1b of a part for positioning the respective reinforcing materials. Thus, a quantity of reinforcing material can be reduced more than a conventional quantity, and workability of its arrangement work can be improved. COPYRIGHT: (C)2006,JPO&NCIPI
