Abstract
Althoughthe strengthening of reinforced concrete (RC) structures using externally bonded fiber-reinforced polymers(FRPs) have been widely accepted as an excellent technical solution for structural strengthening, only few studies have been conducted to understand and predict the behaviourof FRP-to-concrete bonded joints under cyclic loadings. This paper summarizes the results of a theoretical study aimed at investigating the effect of the shape of bond-slip models on thebehaviour of the FRP-to-concrete bonded interfacesunder cyclic loading. Two bond-slip model shapes, one with a linear descending branch and another with an exponential descending branch were used in this study. Evolution of damage for each bond-slip model was defined using the existing test data on Carbon FRP (CFRP)-to-concrete bonded joints under cyclic loading. These bond-slip models were then used to predict the behaviourof a CFRP-to-concrete bond jointsubjected to cyclic loading. The results are then compared with the experimental results from a CFRP-to-concrete single shear pull off test under cyclic loading
