Abstract

Note from the Editor The Indonesian archipelago is one of the most active tectonic zones in the world. Therefore to design an important (and dangerous) structure such as a nuclear power plan knowledge of the seismicity of the site is very important. This could be achieved by doing a site-specific seismic hazard analysis. A site-specific seismic hazard analysis is required in the design state in order to determine the recommended seismic design criteria of the structure. A complete and thorough explanation of the methodology to do a site-specific seismic hazard analysis is presented in this Technical Note Abstract in Bahasa Indonesia :

Abstract

This paper presents a site-specific seismic hazard study to determine the recommended seismic design criteria for Suramadu Bridge. The study is performed using probabilistic seismic hazard approach to determine maximum acceleration and response spectra at bedrock and followed by local site effect analysis to determine maximum acceleration and response spectra at ground surface. The probabilistic seismic hazard analysis (PSHA) is carried out using 3-dimension (3-D) seismic source models (fault source model). Two hazard levels are analysed to represent 150 and 3,300 years return period of ground motion around site location. The local site effect analysis is performed using 1-dimension (1-D) shear wave propagation theory to obtain peak ground acceleration and response spectra at ground surface. Finally, the site-specific surface response spectra with 5 percent damping are developed based on the mean plus one standard deviation concept from the result of local site effect analysis.
