Debonding Prediction of RC Beam Flexurally Strengthened with Prestressed FPR

Article Preview

Abstract:

Intermediate crack debonding is a common failure mode of reinforced concrete (RC) beam flexurally strengthened with externally bonded prestressed fiber reinforced polymer (FRP). This study analyzes the effects of flexural cracks and interface softening behavior on the interface shear stress of RC beam strengthened with prestressed FRP under three-point bending loads, and presents an analytical solution for the FRP axial force at the flexural crack section of the strengthened beam. By regarding the interface fracture energy as the debonding criterion, a new theoretical model to predict the debonding load-carrying capacity of RC beam strengthened with prestressed FRP is proposed.
