Abstract

Ground motion prediction equations (GMPEs) have been widely used in various earthquake engineering studies such as probabilistic seismic hazard analyses, scenario-based earthquake hazard map, ground motion, and uniform hazard response spectrum. This equation contains parameters of seismic source path, and site effects. However, previous studies only developed GMPEs without considering site effects. The purpose of this study is to develop a GMPE model considering site effects. Site condition was classified with Vs30 data for seismic stations, where Vs30 was the average shear wave velocity over a depth of 30 m from the ground surface. This study validated the proposed GMPE model using event residuals between calculated and recorded ground motion recording data for Korean earthquakes.
