Abstract: This paper investigates the torsion behavior of reinforced concrete beams strengthened with glass fibre reinforced polymer (GFRP). The effect of GFRP wrapping on the torsion strength of the beam is examined. There are two group of beam. Group 1- Two of the beam was used as a control beam and Group 2- Four beams were strengthened using different configurations and different types of GFRP fabrics. Totally Six test beams are made with normal steel bars. Beams are made with 40 % replacement of fly ash in cement. All the beams were designed to fail in torsion. The study is restricted to continuously wrapped GFRP fabrics. The experimental study shows that the GFRP wrapping increase the torsion strength of the reinforced concrete beams. The beams will be numerically analysis using ANSYS Software. Load deflection relation as well as torsion twist angle relations were drawn and behavior comparison. In this Full Wrapping pattern gives a better result than the other beams.
