Abstract:An analytical model is developed in this work to derive the bond-slip relationship at the reinforcement-substrate concrete interface (joint) for externally bonded FRP (EB-FRP). The model is generally applicable to both long joints (infinite bond length) and short joints. The bond-slip relationship for short joints with a limited bond length is a general model for EB-FRP joints. When the bond length approaches infinity, the model degenerates to a well-known existing analytical model. It is concluded from the modeling that the existing model for long joints is not applicable to short joints that have a bond length that is less than the effective bond length, or at locations in long joints that are closer than the effective bond length to the free end of the reinforcement. The bond-slip relationship is verified with test results.
