Abstract
In recent seismic design codes, accelerograms recorded in areas with similar conditions to the target site are required for seismic analysis. When there are no available recorded ground motions of sufficiently large intensities, small intensity ground motions need to be appropriately amplified. In this study, the Empirical Green’s Functions (EGF) method by finite earthquake fault modeling was used for this purpose. The high frequency filter according to the distance between earthquake source to site was applied. The regression analysis of spectral acceleration amplifications by magnitude and hypocentral distance was performed. Finally, the methodology to determine an optimum condition for converting the recorded accelerogram into ground motion time histories compatible with the Design Response Spectrum (DRS) was suggested.
