Abstract: This paper presents the nonlinear Finite Element Analysis (FEA) that has been carried out to simulate the behaviour of failure modes of Reinforced Concrete (RC) beams strengthened in flexure by Fibre Reinforced Polymer (FRP) laminates. Two beams were modeled in FEM software using ANSYS. In those two beams, one beam is control beam without FRP and other beam is Glass Fibre Reinforced Polymer (GFRP) strengthened beams. From the analyses the load deflection relationships, crack pattern, first crack load and Ultimate load was obtained and compared with the experimental results available in Literature. The load deflection plots obtained from numerical studies show good agreement with the experimental plots. There was a difference in behaviour between the RC beams strengthened with and without GFRP layers. Therefore, modeling of experimental beams can be adoptable in ANSYS. Validation of experimental results can also be done using ANSYS.
