Abstract :
This paper offers a method to use deterministic attenuation relationships in probabilistic seismic hazard analysis (PSHA). For a given magnitude and epicentral distance, deterministic attenuation relationships evaluate strong ground motion definitely, so analyzer must assume a standard deviation for the attenuation relationship in the PSHA. This study proposes a PSHA method which can apply the attenuation relationship without standard deviation. Required uncertainty for PSHA is obtained through the uncertainty in magnitude. Seismic source is modeled as a convex combination of three Gaussian distributions. The method is tested for Milad tower site and the results are in accordance with previous studies.
