Abstract

Debonding of fiber reinforced polymer (FRP) is a main premature failure of RC beams strengthened with FRP plate, which is mainly due to the interfacial slip between FRP and concrete beam. The interfacial slip is one of the key factors to affect the behaviors of RC beams strengthened with FRP plate. Under external loading, the relative slip occurring on the interface between FRP plate and concrete beam causes the redistribution of stress and then the bearing capacity of the member is reduced. According to elasticity theory, this study analyzes the theoretical analysis of interfacial slip of RC beams strengthened with FRP plate under symmetry concentrated loading. The analytical model is established, and the differential equation of interfacial slip of RC beams strengthened with FRP plate is established. Using the boundary conditions, the calculated formulas of interfacial slip are deduced under symmetry concentrated loading.
