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
