An Experimental Study on Strengthening of Reinforced Concrete Beam using Glass Fiber Reinforced Polymer Composites

Objective: This work deals with the experimental investigation on the study the effect of glass fiber reinforced polymer composite sheets in RC beam. Methods/Statistical analysis: An experimental setup is placed the specimens on the loading frame for flexure and shear behaviour of RC beams. Findings: Determining the load, deflection and failure mode of each beams and their results (beam F2, F3) are compared with controlled concrete beam (F1). The beam F2 has initial flexural cracks appeared at higher load than beam F1.The ultimate load carrying capacity of beam F2 is 35%, which is higher than beam F1. Applications/Improvements: The beam with GFRP sheets upto neutral axis of beam, which is increasing the ultimate load carrying capacity.
