Abstract

Strengthening and repair of concrete structures using externally bonded fiber reinforced polymer (FRP) composite sheets has been popular around the world during the last two decades. However, premature failure due to debonding of the FRP is one of the important issues remaining to be resolved. Numerous research studies have dealt with the debonding problem in terms of bond strength, bond stress-slip relationship, effective bond length, and the interfacial fracture energy. Determination of the effective bond length is still not completely understood. This paper summarizes previous work on effective bond length and proposes a new relationship for effective bond length with FRP stiffness based on existing experimental data collected in this study
