【Abstract】 Based on low-period cyclic load tests of compound damper with concealed X type mild steel lead and mild steel damper,this paper carried out theoretical analysis of the compound damper.The theory hysteretic curves of the dampers fit well with tested hysteretic curves of the dampers,and in the paper a hysteretic model for the compound damper is suggested.The damper is used in the energy dissipation system of a suspension structure.Then,the time history analysis of earthquake responses of the energy dissipation system is carried out.The results show that the energy dissipation system of the compound damper with concealed X type mild steel lead is of good seismic performances.更多还原
