Seismic Design of Pile-Supported Wharves: Effect of New Steel Strain Limits in ASCE 61-19

A study of Harn et al. (2019) has concluded that steel pipe piles may suffer from premature buckling failure before reaching the strain limits in ASCE/COPRI 61-14 Seismic Design of Piers and Wharves (ASCE 61-14). Revised strain limits to prevent premature buckling have been proposed based on the piles’ D/t ratio which are much lower than the current strain limits for piles typically used for pile wharf design. This paper presents the results of a study carried out into effect on predicted performance with the revised strain limits on a typical container wharf. The options for adjusting the pile design to give a similar performance as predicted with the current strain limits have been investigated. Furthermore, the effect of a possible increase in plastic hinge length for piles founded in soft clays has also been briefly studied.
