【Abstract】 By using the BencWen model to represent the nonlinear hysteretic restoringforce character of the isolation bearings,and by using the equivalent linearization method for random vibration evaluation, dynamic responses of baseisolation building are studied. Wilsonθ mechod and linearized acceleration method are used to calculate the timehistory of seismic response of a base isolation builing. The results indicate that the Bencwen model and the equivalent linearization method are satisfied for examining the restoringforce character of the isolation bearings.更多还原
