  1. So this base isolation technique has profound prospects. unfortunately there exist definite difficulties in the calculation because of the nonlinear of the base friction force. now, both the equivalent damping method and the numerical calculatin of the vibration response of the base - isolated buildings are frequently used in the calculation of the seismic response of the base - isolated building. however both of them have certain drawbacks. in this paper, the response of the building with base - isolation system is derived by the method of fourier expansion for the friction force and the earthquake response. at the same time, the sliding vibration character of inertia of a single mass structure and the sliding vibration response of a muti - mass structure are discussed. the stable condition of the sliding base isolation system of a structure is given. in the end, two circes of base fixation and base sliding are analyzed by adopting ansys

    本文利用對摩擦力和地震響應進行付氏級數展開的方法導出了基底具有摩擦隔震系統的地震反應。同時，文中從研究單質點結構的滑動振動慣性力入手，進而對多質點結構體系滑動振動反應進行探討，分別給出了結構滑動隔震的自身穩定條件。最後，本文利用ansys對基礎固定和基礎滑移隔震兩種工況進行了動力模擬模擬分析，進一步證實了基礎滑移隔規律。
