摘要：

This paper presents a theoretical study aimed at predicting the behaviour of carbon fibre reinforced polymer-to-concrete bonded joints under fatigue-cyclic loading. A model considering the plastic deformations of the interface, the damage, and the damage accumulation due to fatiguecyclic loading is proposed. The damage accumulation model is calibrated through the experimental bond-slip relation. Then, a numerical algorithm is formulated to simulate the fatigue bond behaviour using the calibrated damage accumulation model. Numerical simulation was found to provide conservative predictions for fatigue life, which was attributed to the neglect of beneficial effects from the compression stress state near the loaded end in the single-shear pull-off test.
