Abstract

A comprehensive collection of 422 powerful ground motion recordings was created by the earthquake in Chi-Chi, Taiwan. In this study, we use the DEEPSOIL V7.0 software to show some of the results of our analysis. The results indicate the modified record with PGA = 0.2g shows a higher intensity of ground motion compared to the original PGA = 0 .18g. In addition, the spectral acceleration peaks suggest maximum seismic demand at 0.2-1 sec periods, while the fourier phase angle variations indicate wave propagation complexities that may require additional site-specific studies. These findings play an important role for seismic hazard assessment, earthquake-resistant structural design, and geotechnical engineering applications.
