Abstract: Recent experiences have demonstrated that earthquake-induced damage to wharf structure is highly susceptible to batter piles.In the United States,wharf structures without batter piles attached are commonly constructed in seismically active regions,however,batter piles are still being advocated in new wharf designs in China.In order to better understand seismic performance of batter piles,elastic-plastic time history analysis is implemented for two cases using ABAQUS.The first case analysis is carried out wi...
