A simple artificial earthquake considering uncertain geophysical properties of soil ground from the source-to-site and faulting process in a source region are presented as a random earthquake ground motion model. Within the mathematical idealization considered here, the entire transmission path and the faulting process are assumed to be random. Fault rupture is modeled as a superposition of subevents which occure along fault length presented here according to a uniform distribution. From results on the characteristics of artificial earthquakes and their response spectra, it is suggested that the rupture direction, velocity and the relative position between the focus of an earthquake and the site have tremendous effect on the evaluation of peak ground motions and response of structural systems especially in the near field. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
