Background
An earthquake is a very serious natural disaster and causes huge damage to building structures. The current scientific technology is not enough to make accurate prediction of the occurrence of earthquake, so at present, the important point of earthquake-proof research is how to effectively enhance the earthquake-proof capability of the structure. In general, a conventional anti-seismic method is intended to consume energy input into a structure by receiving energy and breaking the energy through a member of the structure itself in a manner of simply improving material strength, member size, reinforcement ratio and the like. By using the traditional anti-seismic method, structural members of the structure can be seriously damaged after an earthquake occurs, and even some buildings can directly collapse. Moreover, while the rigidity of the structure and the strength of the material are improved blindly, the cross section of the building is increased, but the use area in the building is greatly reduced, which causes the waste of building materials and also sharply increases the construction cost of the building.
The installation of dampers in building structures can effectively reduce this destructive effect. However, the displacement input into the damper is affected by various factors so that the damper does not function effectively. The displacement input into the damper is amplified, so that the problem that the performance of the damper is influenced due to the fact that the displacement between the structural layers is too small can be well solved.
