PROBLEM TO BE SOLVED: To provide a reinforcing method for a building structure which can improve strength and toughness with effective earthquake resistance and damping performance.SOLUTION: In a reinforcing method, a plurality of steel plates 31 are faced each other on surfaces of an existing column (building structure) 1 so that the column 1 is surrounded. Then, spaces between the surfaces of the column 1 and the laminated steel plates 31 are filled with grout materials 61, longitudinal ribs 391 projecting inward and extending in a vertical direction are formed in side edges of the adjacent steel plates 31, so that the longitudinal ribs 391 are overlapped each other to be contacted. Connection strength of the steel plates 31 to the grout materials 61 are enhanced via the longitudinal ribs 391. The longitudinal ribs 391 are contacted each other so as to restrain the movement of the steel plates 31 in a horizontal direction and improve earthquake resistance or the like. |
