| 總結: | Seismic hazard analysis and design spectral response for Suramadu bridge was done to
accommodate the lack of Indonesia seismic hazard map that fulfill the requisite design
criteria on Bridge Management System and International Building Code 2006, which is
4950 return period that accommodate 100 years bridge design life and 2 % probability
of exceedance. Seismic hazard analysis software named EZFRISK that used in this
researh was using a total probability theorm and the 3D earthquake source model which
based on the seismotectonic and regional fault identification using the reginal geology
map. Seismic source area which contribute the site location assumed to have a radius of
500 km from the Suramadu bridge location. 1 dimensional wave propagation from
bedrock to the surface was done using NERA software which required soil stratification
and shear wave velocity parameter as input parameter. Seismic hazard analysis using
the same return of period show that maximum acceleration on bedrock and at the
surface according to SNI-1726-2002 for Surabaya region was lower than the analysis
using the 3D earthquake source model. Therefore a detailed evaluation and examination
to the Indonesia hazard map on SNI-1726-2002 must be done. A standard seismicity
parameter and guideline to make Indonesia seismic hazard map was needed to avoid the
publicity of different variation of Indonesia seismic hazard map in the future. |
