PROBLEM TO BE SOLVED: To provide an earthquake-resistant structure which can reduce reinforcement of a peripheral member.;SOLUTION: A corrugated steel plate 40 for reinforcement is joined to a repair area 28A of the top and bottom parts of a corrugated steel plate 28 during repair. Because of this, the areas which have different shearing rigidity are formed in the top and bottom parts of the corrugated steel plate 28, and the repair area 28A to which the corrugated steel plate 40 for reinforcement is joined has larger shearing rigidity than the other area 28B to which the corrugated steel plate 40 for reinforcement is not joined. Namely, the shearing rigidity in the other area 28B becomes relatively small, and the other area 28B yields by smaller inter-layer deformation than before the repair. Therefore, when inter-layer deformation appears in the frame 12, the absorbing capacity of vibrational energy by a history loop becomes larger since the other area 28B yields at an early stage.;COPYRIGHT: (C)2010,JPO&INPIT
