| Abstract: | Based on the superelasticity of shape memory alloy(SMA),a vibration-mitigation device,known as SMA incorporated friction damper is developed by combining the SMA wires with the friction damper.The design procedures and working mechanisms of the SMA incorporated friction damper are presented in this paper first.Then,a theoretical model of the developed damper is established.According to this theoretical model,the force-displacement hysteretic loops of the damper are obtained.Finally,dynamic responses of a SMA incorporated friction damper controlled SDOF system under earthquake action are simulated.The numerical results show that the proposed damper device has excellent energy dissipation capacity. |
