Background
The earthquake can cause strong damage to the structure, and particularly, the middle earthquake and the large earthquake can cause the collapse of the structure. Like the domestic Tangshan earthquake and Wenchuan earthquake, the earthquake-resistant steel plate brings heavy cost to people. The reason why the earthquake causes great damage to the structure is mainly that the existing structure does not have the capability of completely resisting the complex earthquake, and the structure can be subjected to the earthquake action stronger than the fortification intensity, so that the serious damage is caused to the structure. Some structures maintain the integrity of the whole structure after the earthquake so that the structure does not collapse, but the structure generates larger plastic deformation in the earthquake process, so that the structure has larger residual deformation after the earthquake. The existence of the residual deformation of the structure after earthquake can seriously reduce the capability of the structure for resisting aftershock, and the cost for reinforcing and repairing the structure after earthquake is increased, even the structure needs to be overturned for reconstruction, when the residual lateral displacement rate reaches 0.5 percent, McCormick finds that the cost for repairing is higher than that for reconstruction, and when the residual lateral displacement rate of the structure reaches 1 percent, the psychology and physiology of a resident can be uncomfortable to influence the normal life of people, so the residual deformation of the structure after earthquake is an important performance index which needs to be considered in the design of the earthquake-resistant performance of the structure. The self-resetting of the post-earthquake structure can effectively solve the problem of permanent displacement, so that the self-resetting structure is more and more favored by broad students and researchers.
In order to improve the shock resistance and post-earthquake restorability of the structure, which have been studied by some scholars in recent years, the self-resetting structure should be used in combination with some energy dissipation devices, so that the maximum deformation and residual deformation of the structure can be reduced at the same time.
