Accurate seismic structural analysis is essential to ensure the safety of bridges. The nonlinear seismic behavior of bridge structures generally exhibits distinct difference in the longitudinal and transverse directions, and thus is sensitive to the selection and modification of the input ground motion records. Performance-based earthquake engineering (PBEE) methodology explicitly takes into account uncertainties in hazard, structural response, damage, and loss estimation. Therefore, PBEE enables a comprehensive understanding of the structural performance in a probabilistic manner. For a given large earthquake scenario, this study takes advantage of the PBEE methodology to develop a reference benchmark probability distribution of seismic demands (PDSD) for a given bridge structure considering different intercept angles of the input ground motions. The accuracy and reliability of all PDSD estimates from various ground motion selection and modification (GMSM) procedures are evaluated against this reference benchmark PDSD. Such evaluation is conducted for several engineering demand parameters (EDPs) of three representative RC highway bridges.
