Behaviour of R.C Beam and Glass Fiber Reinforced Polymer Composite Beam for Shear Strength

AbstractFiber- reinforced polymer (FRP) application is a very effective way to repair strengthens structures that have become structurally weak over their life span. FRP repair systems provide an economically viable alternative to traditional repair systems and materials Experimental investigations on the shear behaviour of RC beams strengthened using continuous glass fiber reinforced polymer (GFRP) sheets are carried out. Externally reinforced concrete beams with epoxy- bonded GFRP sheets were tested to failure using a symmetrical two point loading system. The strengthening of the beams is done with different amount and configuration of GFRP sheets. Experimental data on load, deflection and failure modes of each of the beams were obtained. The detail procedure and applications of GFRP sheets for strengthening of RC beams is also included. The effect of number of GFRP layers and its orientation on ultimate load carrying capacity and failure mode of the beams are investigated
