Analysis of energy dissipation and earthquake mitigation of a high-rise building with metal dampers

In order to research energy dissipation and earthquake mitigation effect of metal dampers in high-rise building,elastoplastic time history analysis of a high-rise isolated structure was implemented under imput of intensity 8 strong earthquake,and then the authors contrasted natural vibration period and vibration model,ploted interstorey drift angle curve of the structure under the action of three kinds of seismic wave,and carried out an comparative analysis.The calculation results show that energy dissipation characteristics of the metal damper is favorable,the damper decreases obviously interstorey drift angle and the destruction of wall and coupling beam of high-rise building,achieves a good energy dissipation and earthquake mitigation effect.The result obtained can provide a reference to application of metal damper to earthquake isolation of high-rise buildings.
