PROBLEM TO BE SOLVED: To provide a reinforcement structure capable of increasing a proof stress of a main reinforcement for a column and capable of reducing a cross-sectional area of a column.SOLUTION: A reinforcement structure 1 includes a plurality of main reinforcements 21 for a column 2 to be joined to a beam 3. A yield point or 0.2% proof stress of at least a part of the main reinforcement 21 for the column 2 is greater than a yield point or 0.2% proof stress of a normal reinforcement, which is specified by JIS G3112. Additionally, the column 2 includes a plurality of shear reinforcements 22 for the column 2, which are arranged in such a manner as to surround the main reinforcement 21 for the column 2 in a plane crossing the axial direction of the main reinforcement 21 for the column 2. Yield points or 0.2% proof stresses of the plurality of shear reinforcements 22 for the column 2 are greater than the yield point or 0.2% proof stress of the normal reinforcement. |
