Proposed Seismic Detailing Criteria for Piers and Wharves
A new ASCE standard, Seismic Design of Pile Supported Piers and Wharves, is being developed by the Coasts, Oceans, Ports, and Rivers Institute. The standard will use displacement-based methods and build on the provisions of similar standards such as the Marine Oil Terminal Engineering and Maintenance Standards, the Port of Long Beach Wharf Design Criteria, and the Port of Los Angeles Container Terminal Seismic Code. As part of the development of the proposed standard, a significant effort was expended reviewing test data for a wide variety of deck systems and pile- to-deck connections commonly used throughout North America. A common finding of the tests is that the rotation at the pile-to-deck connection is concentrated at a large crack at the interface between the pile and the deck rather than over a short length of the pile at the top of the pile, which is the expected behavior for reinforced concrete in flexure. This paper focuses on the detailing of pile-to-deck connections and summarizes the available test data for the connections that are considered in the proposed standard, along with permitted strategies for reducing earthquake damage at pile-to-deck connections.
