    With the constant deteriorating of concrete structures and high cost of reconstruction, the need to strengthen them as they age is very important. One of the ways is the use of Fiber Reinforced Polymers (FRP). For the past two decades, research into the use of FRP to strengthen existing concrete structures is on the rise with the bond between FRP and concrete of high importance. With the evolution of these research fields, time is of the essence in this engineering world hence a valid finite elemental model will be of immense contribution. This current research seeks to analytically analyze the bond shear strength between FRP and concrete using ANSYS software.  A control model is initially developed and compared with experimental and theoretical data developed by J. Yao et al. and, J.G. Teng and J.F. Chen respectively. The near-end supported (NES) single-shear pull test method was used.
