| Abstract | The final report that accompanies this appendix 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. This appendix (Appendix B) documents the first of two design examples prepared to guide engineers through the application of the American Association of State Highway and Transportation Officials (AASHTO) Seismic Guide Specifications to the Highways for LIFE precast bridge bent system, along with the supplemental design provisions that have been proposed as an appendix to the Seismic Guide Specifications. Particular emphasis is given to the design and detailing of the connections between precast elements to ensure ductile energy dissipating behavior within the plastic hinge regions of the columns and capacity protection throughout the remainder of the structure. This design example uses an actual bridge recently designed by Washington State Department of Transportation, the US 12 Bridge over Interstate 5 at Grand Mound, which is also the demonstration project described in chapter 5 of the project report. |
