Comparison between the Effects of Near- and Far-Fault Ground Motions on the Seismic Response of a Soil-Pile-Structure System

Ground motions recorded in near-fault sites, where the rupture propagates toward the site, are significantly different from those observed in far-fault regions. In this research, finite element modeling is used to compare the effects of near- and far-fault ground motions on a system consisting of so...
