CARBON FIBER COMPOSITES FOR REHABILITATION OF BRIDGE BENTS

The rehabilitation of a reinforced concrete pier of the Highland Drive bridge on Interstate 80 in Salt Lake City, Utah was undertaken using carbon fiber composite materials. This project is unique because it deals with gravity and seismic issues as well as corrosion related problems. The project examined column wrapping as well as wrapping portions of the cap beam and three cap beam-column joints. This paper describes the analysis and design procedures for the carbon fiber composite wraps used on the retrofitted pier of the I-80 Highland Drive bridge. In addition, full-scale laboratory tests of retrofitted cap beam-column joints similar to those of the rehabilitated pier are described. The objectives of this research were to: (1) Restore the capacity of the bridge pier for gravity loads and improve its seismic resistance. This included the design of the pier retrofit for the columns, cap beam, and cap beam-column joints, and the performance of full-scale laboratory tests to evaluate the retrofit measures. (2) Demonstrate the feasibility of repairing a bridge bent using carbon fiber composite materials. the field demonstration provided valuable information on the practical aspects of applying this technology.
