Building structures are spaces in which people rely on survival and production, and the performance of the building structures under the action of earthquakes is very important to casualties and property damage. At present, the earthquake-proof design principle of the building structure in China is 'small earthquake damage-proof, medium earthquake repairable and large earthquake collapse', earthquake energy is dissipated mainly through elastic-plastic deformation of structural members, so that the building structure is inevitably damaged in different degrees and has larger residual deformation after strong earthquake, the structure is difficult to repair and loses the use function, and the final structure can only be overturned and rebuilt. The installation of dampers in building structures can effectively increase the damping of the structure, absorb and dissipate the vibrational energy transmitted into the structure, and reduce the dynamic response of the structure. Currently, dampers are widely used in the field of earthquake resistance and wind resistance of engineering structures, and commonly used dampers generally include: metal yielding dampers, lead dampers, friction dampers, viscoelastic dampers, viscous fluid dampers, electrical induction type energy dissipaters, electromagnetic fluid dampers, composite dampers and the like.
Although the damper is arranged in the structure, the anti-seismic performance of the structure can be improved, and the damage of the structure can be reduced, the common damper has poor damping effect and does not have self-recovery capability, so that the residual deformation of the structure after the earthquake cannot be eliminated or reduced, and the recovery function of the building structure after the strong earthquake cannot be improved.
