| 摘 要： | 本建立了滞变－摩擦基底隔震系统在地震作用下的运动微分方程，并将地震地面运动模拟成均值为零的两次过滤Ｇａｕｓｓ白噪声过程。使用等效线性化方法求解了这种隔震系统的地震反应统计特征，并分析了这种隔震系统参数的变化对其反应统计特征的影响。

| Abstract: | The differential equations of motion of a hysteresis friction base isolation system under earthquake action are established and the earthquake ground motion is modeled as a twice filtered Gaussian white noise process with zero mean.The earthquake response statistics of the isolation system are solved by using thee quivalent linearization method and the influence on the response statistics produced by varying parameters of the isolation system is analysed. |
