摘要

A new approach of spatially correlated and non-stationary earthquake ground motions based on phase difference spectrum is presented. The independent non-stationary accelerograms of the reference points, specified for each different type soil, are simulated by the inverse FFT, in which the Fourier amplitude spectrums are compatible with the specified power spectrum density functions and the Fourier phase spectrums are simulated on the basis of the empirical model of the phase difference spectrum. The spatial correlated and non-stationary earthquake ground motions are simulated by the best linear unbiased estimation technique, on the conditions of incoherency function and reference ground motions.
