Abstract: The main reasons resulting in the poor seismic performance of the open type wharf with standing piles are clarified by examining extensive documented case studies of the damaged pile-supported wharves. The state of the art of the research on the open type wharf with standing piles, from the aspects of the seismic design methods, soil-pile interaction, seismic performance of the batter piles and pile-deck connections, is presented, and the applications of the research findings from the seismic codes for the pile-supported wharves are summarized, and the deficiencies concerning the researches and the problems needed to be further studied are pointed out. Some suggestions to revise the domestic seismic design codes and specifications are made. This is the third part of the series papers which discuss the seismic performance of the batter piles and pile-superstructure connections. The research results show that there is a great controversy in the seismic performance of the batter piles, and extensive theoretical and experimental studies on the pile-superstructure connections as well as the isolation technique have been carried out and the related findings applied to the seismic design of the wharves. And subsequent researches should be still conducted on the usage of the batter piles and pile-superstructure connections.
