In addition, according to the third structure of the present invention, the frame opening is covered in the left and right direction within the frame opening defined by the columns and beams of the structure. By arranging a plurality of FRP reinforcing panels vertically, it is possible to obtain the same excellent seismic strengthening effect as when a waist wall is provided from the floor side and a leaning wall is provided from the ceiling side. Since the reinforcing panel is lightweight, construction work such as mounting is easy, the construction period can be shortened, and a large load is not applied to the structure. In addition, a brace was provided in the frame opening as in the case described above by interposing a stress transmitting member having a rigidity corresponding to the strength required for the frame opening between the FRP reinforcing panels. The same seismic strengthening effect as in the case is obtained, and the desired seismic strengthening can be performed by adjusting the rigidity of the stress transmitting member, and the same reinforcing effect as when a column (stud) is provided. In addition, it is possible to obtain an effect of increasing the strength against a long-term load and an effect of reinforcing the earthquake. In addition, in such an earthquake-resistant reinforcement structure, since construction can be performed using an adhesive or the like without using an anchor, “construction while staying” can be performed, and a prolonged construction period can be prevented.
