Abstract: As Hundreds of new materials appear on the market each month, each of these materials has its characteristics, applications, advantages, limitations and cost. Thus, the task of knowing the properties and behavior of all types numerous studies has been carried out. Life cycle assessment has become an important tool for determining the overall performance of component. So, nonlinear Finite Element Analysis (FEA) has been carried out in this paper to simulate the behavior of failure modes of reinforced concrete (RC) beams strengthened in flexure by fiber 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 Fiber Reinforced Polymer (GFRP) strengthened beams. From the analyses the load deflection relationships, maximum deformation, factor of safety, von-misses stresses, 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 behavior between the RC beams strengthened with and without GFRP layers.
