Computation and Application Research of Earthguake Response Spectra for Isolating Structure

The authors establish the time analytical method of the earthquake response for the isolating structure on base of the simple mode suggested by paper 1] and 2], and compute the response spectra of the supper structure acceleration and the base displacement. The authors carry out a reseach into the earthquake response characteristic and the choice for the parameters of isolating bearings. The method is analytical, accurate, reliable, useful and meaningful for establishing the design method of the isolating structure and popularizing application.
