Abstract:

In today's today lifestyles, it's miles vital to alter, restore, rehabilitate, or reconstruct present structures due to the various factors like bond failure among the beam and column joint, corrosion, which results in deterioration, natural failures, etc. These factors affect in cracking of the structures. That is, the structures turn unserviceable. Hence the modification of those structures could be very much required. Consequently, structural enhancing or strengthening and retrofitting constructed structures have become vital aspects of the production enterprise. Nowadays, FRP composites gain a good deal reputation due to their excessive energy to weight ratio, minimal fee/cost in structural geometry, smooth and rapid and corrosion, and fatigue resistance. In this experimental study, the mechanical behavior of reinforced concrete beams wrapped using glass fibers is studied. The beams were cast out of which one was a control beam, and the other beams were used for different patterns of GFRP wrapping, which is three sides, two sides, bottom side wrapping. As a result, it was found that GFRP wrapping strengthens the beams by delaying the initiation of cracks.
