A large number of reinforced concrete bridges in the U.S. are structurally deficient by today’s standards. The main contributing factors are changes in their use, an increase in load requirements, or corrosion deterioration due to exposure to an aggressive environment. In order to preserve those bridges, rehabilitation is often considered essential to maintain their capability and to increase public safety (Seible, et al. 1995; Kachlakev 1998).
In the last decade, fiber reinforced polymer (FRP) composites have been used for strengthening structural members of reinforced concrete bridges. Many researchers have found that FRP composite strengthening is an efficient, reliable, and cost-effective means of rehabilitation (Marshall and Busel 1996; Steiner 1996; Tedesco, et al. 1996; Kachlakev 1998). Currently in the U.S., the American Concrete Institute Committee 440 is working to establish design recommendations for FRP application to reinforced concrete (ACI 440 2000).
