Based on the practical simplified model of base-isolated system proposed in [1][2], this paper establishes a corresponding time-history analysis method for seismic response of structures, and calculates the acceleration response spectrum and basic displacement response spectrum of superstructure under the action of seismic waves. On this basis, the seismic response characteristics of isolated structures and the selection of seismic isolation parameters are analyzed. The calculation method provided in this paper is an analytical method, accurate and reliable, with strong applicability, and a practical design method for building seismic isolation structures. The application of this system has a certain significance.
