    Abstract

    Although the use of composite materials has increased significantly over the years, its application to civil engineering structures has been limited. High strength, corrosion resistance, and electromagnetic neutrality make fiber reinforced plastics (FRP) suitable candidates in many applications, including strengthening and the development of new members. In this study, the authors establish a new method of strengthening and/or reinforcing concrete structures involving external bonding of pretensioned FRP sheets on their tension zones. An analytical model for the maximum achievable prestress developed in an earlier study is summarized and verified with tests; a remarkable agreement between theory and experiment was found. Additional studies, both analytical and experimental, on the flexural behavior of concrete beams reinforced with prestressed FRP sheets demonstrate the superior performance of the hybrid system and emphasize its favorable strength, stiffness, and ductility characteristics.
