Since the load-carrying capacity of RC beams strengthened with the FRP is dominated by interfacial delaminated failure, the anchorage strength in FRP to concrete bonded joints under shear and the debonding stress transferring behavior at the end parts of flexural concrete members bonded with FRP have...
Instead, a displacement-based approach is described that shows that FRP plated beams can be designed to achieve a higher strength than that of the RC beam by itself no matter when IC debonding first occurs. The mechanics of the analysis approach developed here treat the FRP debonded plate as...

For members with "weak" bond—that is, for members where debonding of the reinforcement defines failure such as fiber reinforced polymer (FRP) plated members—the M/θ approach has been developed and applied to simulate both monotonic [9,31] and cyclic [32] loading. For members with a "...
Partial-interaction due to sliding between the steel bars, adhesively attached FRP plates and their bordering concrete surface, accompanied with the detachment of the FRP plates due to intermediate crack (IC) debonding make the deflection of strengthened RC beams difficult to anticipate. Previous ...
The influence of creep of the concrete and the adhesive on the edge debonding failure load of reinforced concrete beams that are strengthened with externally bonded composite materials is investigated both theoretically and experimentally. The theoretical study includes a stress analysis phase and a ...
A linear elastic fracture mechanics (LEFM) approach to the debonding analysis of concrete beams strengthened with externally bonded fiber-reinforced-polymer (FRP) strips are studied. The analytical models based on the LEFM approach are presented and discussed. The fracture analysis has adopted the ...
