摘要：

A simple and accurate algorithm for nonstationary responses of structures subjected to evolutionary random seismic excitation is presented as an extension of the pseudo-excitation method for stationary random seismic responses. The analyses of various time-dependent auto- or cross-power spectral density (PSD) functions have simple and unified formulae. For some important envelope functions, time-dependent PSD functions can be calculated by means of simple frequency-domain analyses.
