PROBLEM TO BE SOLVED: To add an elasto-plastic damper to an existing structural member in a state the plastic deformation capacity of the existing structural member functions, which is shear-deformed when the existing structural member receives shear force in an in-plane direction.SOLUTION: Plural reinforcement members 4, 4 are disposed at a certain distance from each other in an axial direction along an existing structural member 3 in a direction perpendicular to a plane on which shear force acts to shear-deform the existing structural member 3. The reinforcement members 4, 4 positioned at both sides in the axial direction are joined to structural members 1 respectively. An elasto-plastic damper 5 having a plastic deformation part 51, which can shear-yield when shear force is applied to an in-plane direction, is disposed between the reinforcement members 4, 4 which are disposed at a certain distance in the axial direction. A part segment 31 of the existing structural member 3 is removed excluding both ends in the axial direction while leaving a part in an H-direction. |
