Abstract

The site response effect i.e. soil amplification has caused major structure damages founded on thick soft soils. Banda Aceh, Indonesia is underlain by approximately 70m to 206m thick alluvium. Thus, site-specific ground response analysis of Banda Aceh is necessary to be warranted. Due to the absence of strong motion records during the 2004 Indian Ocean mega earthquake duplication of synthetic strong motions are used in this study. Subsequently, ground response analysis was carried out by using computer programs of NERA. The results of the site-specific ground response studies expose the real Banda Aceh’s soil response during the 2004 Sumatran mega earthquake. Peak ground acceleration at soil site, maximum amplification ratio, the response spectra and fundamental frequency of the maximum response spectra are presented.

Banda Aceh-Indonesia Ground Response Analysis During the 2004 Indian Ocean Mega Earthquake

Chicago, Illinois

The site response effect i.e. soil amplification has caused major structure damages founded on thick soft soils. Banda Aceh, Indonesia is underlain by approximately 70m to 206m thick alluvium. Thus, site-specific ground response analysis of Banda Aceh is necessary to be warranted. Due to the absence of strong motion records during the 2004 Indian Ocean mega earthquake duplication of synthetic strong motions are used in this study. Subsequently, ground response analysis was carried out by using computer programs of NERA. The results of the site-specific ground response studies expose the real Banda Aceh’s soil response during the 2004 Sumatran mega earthquake. Peak ground acceleration at soil site, maximum amplification ratio, the response spectra and fundamental frequency of the maximum response spectra are presented.
