In this paper, the time analytical method of the earthquake response for the isolating structure is estab-lished on the base of the simple mode suggested by authors, and compute the response spectra of the supper structure acceleration and the base displacement. Therefor, authors reseach into the earthquake response characteristic and the choice for isolating bearings. The method is analytical, accurate, reliability, useful and meaningful for establishing the useful design method of the isolating structure and popularizing application.
Keywords: average acceleration; relative acceleration; base displacement; response spectra
