Experimental Study On Strengthening Of Rc Beam Using Glass Fibre Reinforced Polymer Sheets

Many concrete structures around the world suffer from corrosion, lack of detail, lack of connections between lines and lines, additional services, etc. It now needs repair, maintenance, or reconstruction due to various reasons such as. FRP composites are considered an effective method for repairing and strengthening RCC structures. This paper reports the influence of GFRP sheets wrapped around RCC beams for strengthening. Beams of size were cast and tested. Some of them are without GFRPS, and the remaining beams wrapped in different lay-up patterns with 90 and 45 degrees of inclination of GFRP sheets were subjected to shear and flexural tests. Initial crack load and ultimate failure load have been observed and noted. Experimental results indicate a significant increase in the initial and ultimate load-carrying capacity of GFRPS wrapped beams compared to unwrapped beams.
