This study develops an optimal Probabilistic Seismic Demand Model (PSDM) for pile-supported wharves whit batter plies. Four bins with twenty non-near-field ground motions and three typical pile-supported wharf structures from western United States ports are used to determine an optimal PSDM by using Probabilistic Seismic Demand Analysis (PSDA). PSDA is used to compute the relationship between Engineering Demand Parameters (EDPs) and earthquake Intensity Measures (IMs). An optimal PSDM should be practical, sufficient, effective and efficient-all tested through several IM-EDP pairs. It has been found that for these types of structures, the optimal model comprises a spectral IM, such as spectral acceleration and one of several EDPs. These EDPs are considered for local (moment curvature ductility factor), intermediate (displacement ductility factor and horizontal displacement of embankment) and global (differential settlement between deck and behind land) response quantities. The considered PSDMs are a critical component in performance-based seismic design and seismic risk assessment. Results can be used in probabilistic framework for performance-based design developed by Pacific Earthquake Engineering Research (PEER) center.
