In this paper, seismic response of isolated buildings is simulated by using a detailed hysteresis model for sliding bearing, in comparison with the response by the simple bi-linear hysteresis model. It was found that, through the simulation of shaking table tests, the detailed hysteresis model could simulate the seismic response of the frame model better than the simple model. According to the case study on a mid-story building, isolation-layer displacement under small input tends to be smaller and the response of the superstructure larger, because shear force of isolation-layer is affected by initial coefficients and velocity-dependency of friction. Since these trends appear to be remarkable when sliding type is used for all bearings, the detailed model is recommended in such a case.
