| Abstract: | Shape memory alloy(SMA) has super-elastic hysteresis behavior.Recognizing this,a new type SMA damper which is fit for ancient tower is proposed.The bi-linear restoring force model of the new type SMA damper is determined by experiment.A simulation model is built by using the Simulink block in MATLAB.And the seismic responses of an ancient tower model are investigated under the antetype structure and the structure installed the SMA damper.Simulation results show that the SMA damper can reduce seismic respons... |
