Partial-interaction due to sliding between the steel bars, adhesively attached FRP plates and Received 26 May 2019 their bordering concrete surface, accompanied with the detachment of the FRP plates due Received in revised form 9 July 2019 to intermediate crack (IC) debonding make the deflection of strengthened RC beams Accepted 19 July 2019 difficult to anticipate. Previous research and design rules on determining the deflection of strengthened RC beams using FRP plates have opted for a full-interaction moment- curvature design technique where the deflection was measured by either deriving average effective moment of inertia and using elastic deflection equations or integrating the curvature along the beam’s length. Therefore, IC deboning of the plate and the slip resulting.
