Development of a Precast Bent Cap System for Seismic Regions

José I. Restrepo, Eric E. Matsumoto, Matthew J. Tobolski

Abstract

This report develops and validates precast concrete bent cap systems for use throughout the nation's seismic regions. The report also includes a series of recommended updates to the AASHTO Bridge Design Specifications, Guide Specification for LRFD Seismic Bridge Design, and AASHTO Bridge Construction Specifications that will provide safe and reliable seismic resistance in a cost-effective, durable, and constructible manner. The material in this report will be of immediate interest to bridge engineers.
