Precast Bent System for High Seismic Regions

This report is a technical resource that provides background information on the use of a precast bent system for use in high seismic regions. The system is designed for, and intended to be used with, prestressed girder bridges that are built integrally with the supporting intermediate piers. Such piers are built in two stages, with the lower stage placed first to provide support to the girders and the upper stage constructed later to integrate the pier and superstructure. The precast bent system uses precast columns with cast-in-place foundations, precast pier cap beams, and a cast-in-place upper stage pier cap beam. This report provides information on the system concept, as well as the background physical testing for the upper level grouted duct connections and the lower socket type connections. Additionally, the report provides design and construction specifications, describes a demonstration project constructed in Washington State, and discusses lessons learned from the demonstration project. Finally, two design examples are presented to illustrate the design process for the precast bent system for spread footings and drilled shaft foundations.

• Supplemental Notes:
  • This report includes three appendixes published as stand-alone documents: Appendix A: Design Provisions (FHWA-HIF-13-037-A); Appendix B: Design Example No. 1 (FHWA-HIF-13-037-B; and Appendix C: Design Example No. 2 (FHWA-HIF-13-037-C). In addition, two companion reports cover the detailed testing and modeling of the spread footing and drilled shaft foundation versions of the precast column-to-foundation connection: Laboratory Tests of Column-to-Drilled Shaft Socket Connections (FHWA-HIF-13-038) and Laboratory Tests of Column-to-Footing Socket Connections (FHWA-HIF-13-039).
