The aim of this study is to present a probabilistic method for simulating such (referred to as critical) earthquake for a given nonlinear structure which causes larger response on the structure but shows similar characteristics to a given record, referred to as target. The main idea in simulating critical earthquake is modifying the power spectral density (PSD) graph of target. The method is applied on a given nonlinear SDOF structure and it is clarified that a resulted critical earthquake satisfies restriction amplitude and frequency conditions.
