An Evolutionary Spectrum Model of Nonstationary Seismic Ground Motions Considering Extended Source Effect for Engineering Purposes
A novel evolutionary power spectrum model of seismic ground motions is formulated. The model consists of an envelope function and a seismic spectrum. The envelope function of the ground motion is derived based on a rectangular fault model in which rupture propagates along the diagonal line. The spectral characteristics of the ground motion are described by the earthquake source spectrum and the transfer function of the medium. The values of the model parameters are obtained by the earthquake source mechanism analysis and the ground motion spectrum identification. For applications, the ground motion records during the Northridge earthquake are modeled and simulated.
