Innovative Wharf Details: Elastomeric Bearing Pile-Deck Connection and Finned Monopile

In moment frame wharf structures, the pile-to-deck connections are most susceptible to seismic damage. In this paper, Erik Soderberg, Derrick Lind, and Sugi Loni present a fiber-reinforced elastomeric bearing pile connection that improves connection rotation and eliminates potential damage in an operating level earthquake. They also explain how a second detail—adding fins to monopiles near the ground surface—reduces the required pile diameter and length.
