Fibre reinforced polymers (FRP) are becoming a commonly used material in retrofitting and rehabilitating deteriorating concrete structures. Aside from its high strength, FRP is a lightweight, non-corrosive, and relatively cheap alternative to traditional rehabilitation methods. One of the major components of FRP externally bonded to reinforced concrete is the bond and its behaviour at the FRP-concrete interface. Previous studies have investigated debonding of FRP sheets externally bonded to reinforced concrete through experimental testing as well as finite element modelling. This project presents the numerical modelling of CFRP sheets externally bonded to reinforced concrete. Using the finite element analysis software ABAQUS, three specimens of varying bond lengths subjected to double lap shear were modelled and analyzed. The results were discussed and compared to an experimental study previously performed.
