This paper present a new seismic isolation device which assembled sliding friction, energy dissipation and limit, then clarified the work performance and the optimization of its design ideas. The author utilized FEM analysis software ANSYS to establish a parametric model, taking the working condition of single-ring and stress concentration distribution under the yield state as the research object, the shape of the energy loop was optimum designed, and the hysteresis energy consumption performance of seismic isolation bearings was analyzed before and after optimizing. It can be received that energy consumption performance of the seismic isolation bearings improved 32.7% after optimizing. A 6 layer frame structure FEM model was built, at this basis, the seismic responses of fixed structure and sliding seismic isolation structure of foundations were compared. The results indicated that the seismic responses of sliding structures decreased significantly.
