Abstract:
Seismic Hazard Assessment has been done for Shiraz city in this study and four maps have been prepared to indicate the probabilistic estimate of Peak Ground Acceleration (PGA) over bedrock in this area. For this assessment first, earthquake catalogue and main active fault in a radius of 200 km have been gathered and processed and then seismicity parameters by Kijko`s method and Tavakoli`s method have been obtained, after that the results with four attenuation relationships have introduced to the computer program of seismic hazard analysis `SEISRISKIII` and eventually with combination of the outputs by logic tree technique, the isoacceleration maps in four levels of hazard; which are needed for retrofit of building in Seismic Rehabilitation Code for Existing Buildings in Iran; have been calculated. The results show that the ranges of PGA for 75, 225, 475 and 2475 year return periods are 0.10 to 0.17 g, 0.15 to 0.29 g, 0.18 to 0.39 g and 0.26 to 0.66 g, respectively.
