PROBLEM TO BE SOLVED: To provide a reinforced earthquake-resistant wall to improve aseismic performance of a building with good beauty and well lighting. SOLUTION: A reinforced earthquake-resistant wall 10 is arranged on a frame face surrounded by columns 14 and beams 16, for improving aseismic performance of a structure. The wall 10 is formed of a steel plate 12 fixed on the frame face and openings 18 cut aligned in the length-and-width-direction of the plate 12. The openings 18 bring good beauty and well lighting. By making the opening ratio of the opening 18 a predetermined value or higher, the remaining part of the plate 12 will be fractured by bending before shear fracture. Therefor, when a horizontal force acts on the frame, by a seismic load the wall 10 is ruptured by bending. The wall 10 is able to absorb the vibration energy acting on the structure, because it makes its deformation advance by maintaining its reinforcing strength in the bending rupture.
