The Experimental Study On Anti-seismic Ability Of High Axial Ratio Composite Energy Dissipation Shear Wall

In this paper ,a new style energy dissipation damping shear wall--- composite energy dissipation shear wall is studied. Four high axial compression ratio composite energy dissipation shear walls were used as specimens under low-cyclic recycled lateral loads in an anti-seismic ability experiment. Through the experiment observation and result analysis, the formula of shear-bearing capacity and stiffness are established. Satisfactory agreement between the calculating results and experiment results is obtained. In the end, time-path analysis method of SATWE program was used in structure dynamic analysis. Through the project example analysis, the superiority of this system is discussed. The experiment result analysis indicates that composite energy dissipation shear wall has high stiffness and bearing capacity, good ductility and also beneficial results. It can play an important role in an anti-seismic structure by shear force energy dissipation. It has been proved that this system has practice value.
