The major challenge in the modern day civil engineering is to find a suitable method for rehabilitation and strengthening of the existing structures. One such method of strengthening is the use of strips made of fibre reinforced polymers (FRP). In this paper presents the nonlinear Finite Element Analysis (FEA) that has been carried out to simulate the behaviour of reinforced concrete beams strengthened using Carbon Fibre Reinforced Polymers (CFRP) sheets. FE models were developed based on experimental tests conducted by the authors in a previous investigation. Four point bending analysis is carried out for the reinforced concrete beam. Finite element software ANSYS 14.0 is used for modelling and analysis by conducting non-linear static analysis.
