Field deployment of carbon-fiber-reinforced polymer in bridge applications

Carbon-fiber-reinforced polymer (CFRP) materials are an alternative to steel reinforcement and prestressing strands in harsh climates because of their noncorrosive nature, durability, high tensile strength, and light weight. This paper discusses the use of CFRP in bridges in the form of carbon-fiber-composite cable (CFCC). CFCC's unique performance influences the design requirements of members with CFCC reinforcement. The American Association of State Highway and Transportation Officials and Michigan Department of Transportation are developing guidelines that will help highway transportation agencies make decisions about the use of CFRP for prestressed concrete bridge beams.
