Abstract

The reliability of bond is crucial to the performance of concrete structures strengthened with externally mounted CFRP plate. This paper presents a detailed description of a finite element model constructed using ABAQUS 6.10-1, to simulate the behaviour of CFRP-to-concrete bonded joints in single shear pull out tests. Nonlinear finite element analysis with the cohesive surface approach for single shear pull out tests was investigated and validated against existing test results (monotonic and post-fatigue) in order to demonstrate the accuracy of the model. The influence of bond length for different carbon fibre plate stiffness on the ultimate load as well as the de-bonding strain for the post-fatigue analysis was investigated and then compared with existing analytical models. The numerical results suggest that existing analytical models can be nonconservativein estimating the FRP effective bond length in the post-fatigue load regime
