ASCE/COPRI 61-14 “Seismic Design of Piers and Wharves” (ASCE, 2014) is a standard developed by a group of practicing structural and geotechnical engineers, owners, and academics with specific expertise in marine and waterfront infrastructure, intended to reflect the current state of practice for seismic design of pile-supported piers and wharves. ASCE 61 14 offers no guidance to prevent local buckling of the pile shell for either hollow or concrete-filled pipe piles. For the next edition of ASCE 61, a task group was formed to review the available research, evaluate the existing strain limits in the code, and recommend updates, if deemed necessary, to the provisions. This paper summarizes its findings and proposals.
