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.
