【Abstract】 By using hysteretic damping resultin from superelastic deformation of shape memory alloy(SMA),a new type of SMA-rubber bearing for seismic isolation is developed in this paper.A mechanical model of the bearing is established.Based on the simulation analysis for dynamic responses of a SDOF isolation system applying SMA-rubber bearing,the dynamic property is studied in detail.The results show that the SMA-rubber bearing has excellent performance of seismic isolation and energy dissipation.更多还原
