| Abstract: | Kameda adopted the Multifilter technique to calculate the evolutionary power spectra of earthqudke ground motions and established the model for simulating seismic accelerograms.And then Sugito developed the model for predicting strong motion on rock surface In this paper,the model suggested by the authors on the basis of their work can be applied to nonstationary motion simulation for various sites with design spectra;and the response spectrum of motions predicted by the model can approximates to the site design spectrum |
