Due to its exceptional properties such as good tensile strength, serviceability, corrosion resistant, and light weight, externally bonded Fibre reinforced polymer (FRP) is increasingly being utilized to support reinforced concrete (RC) structures. De-lamination of FRP-plate with concrete cover owing the most prevalent type of failure is due to different stress concentration at the bonded plate’s end (stresses at end). The behaviour of the FRP-concrete interface is an important component in preventing debonding failures in RC structures. As a result, for the safe and cost-effective design of externally bonded FRP systems, a deeper understanding of FRP behaviour for concrete interfaces is necessary. The primary goal of this research is to investigate the behaviour of the FRP-concrete interface. Finite element (FE) simulations utilising the ANSYS Finite Element software are used to investigate the interaction behaviour. For the parametric investigation, FE simulation models are built to investigate the impact of various variables on the binding behaviour of FRP and concrete surfaces by altering the width and thickness of the FRP laminate. Different thickness of FRP 2 mm, 4 mm, 6 mm and different widths 75 mm and 100 mm are taken. Based on the results the multi variable nonlinear regression and multi variable logarithmic Finite element (FE) simulations utilising the ANSYS Finite Element software are used to investigate the interaction behaviour. For the parametric investigation, FE simulation models are built to investigate the impact of various variables on the binding behaviour of FRP and concrete surfaces. Regression study is conducted out, and the best fit for the parameters under evaluation is found. The above analysis results are compared with the published work for validation.
