Abstract | The Hyogo-Ken Nanbu earthquake, occurred on January 17, 1995, one of the worst disasters in Japan is evaluated in this study. The acceleration response spectra of this earthquake are calculated from recorded or transformed acceleration data at 11 available sites, located within 65km from the epicenter. The results are further compared to the existing building code ( 1994 UBC) and shown that the current code of seismic design is not sufficient to completely prevent the structures from serious damages when suffered another attack under the same magnitude of Kobe earthquake. The strong motions were recorded by a downhole accelerometers array at Port Island and provided a top opportunity to analyze the soil effects during the Kobe earthquake. The ground responses of Port Island are simulated by using SHAKE9 l, one of the equivalent linear analysis programs, and the results are found to be in a good agreement with the spectra at ground surface calculated from recorded accelerations, but provided more differing distribution than those at underlying strata. In addition to the main shock, the strata responses of Port Island site due to the aftershocks are also analyzed in this study. The result shows that the computed response spectra due to aftershocks are generally in better agreement than those due to the main shock while compared with the recorded spectra. The application and validity of SHAKE91 program are also discussed in this study. |
