On the other hand, near-fault ground motions possess some features such as distinctive pulse-like time histories, high peak velocities, high ground displacement, high peak ground acceleration (PGA) to peak ground velocity (PGV) ratio, and a wide range of accelerations in their response spectra. They produce damaging and impulsive effects on structures, which require some special attention. Most of the past studies have investigated the effects of either long duration or near-fault motions separately for different structures. This study aims to investigate whether the long duration motions or near-fault ground motions produce more damaging effects for bridge piers during an earthquake. In this study, the bridge pier considered is located in Vancouver, BC. The bridge pier is designed following a performance-based seismic design guideline. Using 20 long duration motions and 20 near-fault motions, the collapse performance of the bridge pier will be evaluated. Using Incremental dynamic analysis, the collapse capacity of the bridge pier will be evaluated considering uncertainties in ground-motion characteristics and structural modeling. The outcome of this study will provide an insight on the comparative collapse performance of bridge pier under long duration and near-fault ground motion.
