Application Research On Energy Dissipation Of Viscous Damper In Frame Structures

This dissertation mainly discusses the various arrangements and objective functions of viscous dampers.And an objective function is proposed on the basis of various objective functions.The optimal arrangement of viscous dampers is obtained by analyzing the damping effect of various arrangements.Finally,an installation method of viscous dampers is put forward.The optimal arrangement scheme of viscous damper is obtained by comparing and analyzing the effect of different installation methods and combining with the arrangement method of viscous damper.By comparing the response of the same structure under different seismic waves,the response of the structure is analyzed to verify whether the arrangement scheme of the viscous dampers has good damping effect.Then some relevant conclusions are drawn.The results show that frame structures with viscous dampers have good damping effect during an earthquake.Viscous dampers with the same number have different damping effect in different arrangements and installation for structure mitigation,and a structure has different responses under different seismic waves.Through the comparison of the damping effect of viscous dampers in various arrangements,it is conclude that the optimal arrangement based on the objective function of the displacement between layers has good damping effect.The viscous damping structure based on the installation form of displacement amplification system based on triangle hinge positioning has good damping effect.The optimal arrangement scheme of viscous damper is obtained by combining the different arrangement and installation methods of viscous damper,and the rationality of this arrangement scheme is verified by different seismic waves.It is hoped that the research in this dissertation can provide some reference for seismic design of structures.
