Abstract: The usage of externally bonded FRP system as a way to strengthened RC structures is increasingly popular in the past decade due to their high strength-to-weight ratio and chemical resistance. The failure at the bond interface of a FRP-strengthened RC structure can be modelled using a bond-slip model. Rather than doing the real experimental method of pull-out tests, a meso-scale finite element analysis was carried out to simulate the pull-out tests for a specimen subjected to low slip rate. The bond-slip model provides the peak bond stress and interfacial fracture energy which acts as the key indicators of the structural performance of an FRP-strengthened RC structure. After investigating the local response of the bond using its bond-slip behaviour, the global response such as the RC structure’s overall loading capacity could be included to give a more comprehensive assessment of the structure.
