ABSTRACT Many of the current worldwide reinforced concrete structures urgently need rehabilitation, repair or reconstruction as a consequence of various factors, including corrosion, lack of detail, failure to bind between column beam joints, increases in service loads, and so on. FRP composite has been agreed as a successful substitute for repairing and increasing RCC structural strength.As a composite of fibres-reinforced polymer (FRP), RCC structures increase in strength due to their exceptional properties such as high strength to weight, corrosion and fire resistance, increased fatigue resistance and energy absorption capabilities. This paper is intended for the testing of damaged reinforced concrete beams remedied by the addition of GFP overlays to beams. Analytically and experimentally examined the ultimate load carrying capacity and deflection capacity of the RCC beam and wrapped GFRP beam. The investigation was done with ANSYS software.
