Repair and strengthening of R.C beam is now becoming more and more important in the field of structural strengthening and retrofitting. The present paper reviews the study of Glass Fiber Reinforced Polymer (GFRP) flats under flexural behavior in reinforced concrete beams. In this study, experimental investigation on the flexural behavior of RC Beam has been studied by wrapping Glass Fiber Reinforced Polymer (GFRP) sheets. Reinforced Concrete Beam externally bonded with GFRP sheets were tested to failure using a symmetrical two point static loading system. Six Reinforced Concrete Beams have been cast for this experimental test. All cast beams are weak in flexural and having same reinforcement detailing. Three beams are used as control beams and three beams are strengthened using full bottom of glass fiber reinforced polymer (GFRP) sheets. The experimental result shows, that full bottom GFRP sheet wrapping in 70% preloaded beam can increase flexural capacity of the beam by 14%(on ultimate load) as compared to Controlled Beams.
