Selection of ground motion prediction equations for probabilistic seismic hazard analysis based on an improved fuzzy logic

摘要: The fuzzy logic method has been used widely in civil and earthquake engineering, but there is no comprehensive point of view for utilizing approach order to obtain ground motion prediction equations (GMPEs) probabilistic seismic hazard analysis (PSHA). Hence, magnitude–distance as a new choosing GMPEs the process PSHA, developed this research through selection ruling peak acceleration (PGA) each common cell (the combined intensity site source distance). presented reduces need engineering judgments based on newly benchmark. It enables designers not only determine range acceptable results also introduces concept which ensures initial well-suited analysis.
