Abstract

Studies on the behavior of soil layers reflect the fact that the soil is generally enter the range of nonlinear behavior during strong ground motions that have received increased attention in recent years. Conventional seismic hazard analysis often assumes a linear behaviour for soil with considering of a generic-attenuation relation. Generally, for site response analysis, the AMPLIFICATION FUNCTION is required that is depend on dynamic property of different soil layers, are not known for different parts of the world. This paper is aimed at presenting a straightforward approach for estimating seismic hazard curves taking into account nonlinear soil-site effects. This approach convolves numerically the PROBABILISTIC SEISMIC HAZARD ANALYSIS (PSHA) at bedrock with the nonlinear response of soil computed via dynamic analysis. Applications of proposed method has been shown for two different sites located in Tehran and Tabriz, one sandy and one clayey. A Monte Carlo based approach was used for characterization of AMPLIFICATION FUNCTION values along with those of deterministic curved obtained in the study areas. It is concluded that the proposed model can give satisfactory accuracy for predicting seismic hazard curves when there is a lack of detailed information of dynamic soil properties.
