Abstract


The maintenance, repairing, and rehabilitation of structural individuals, is perhaps one of the most critical issues in civil engineering applications. Glass Fiber Reinforced Polymer (GFRP) software is a very effective way to restore and enhance structures. The bolstered concrete beams of externally bonded epoxy resin with GFRP sheets had been examined to failure by means of the use of a symmetrical two-factor concentrated static loading gadget. The beams have been forged for this experimental take a look at program. The objective of these paintings is to assess the structural conduct of reinforced concrete beams with externally bonded FRP reinforcement. Beams bonded with 4 one-of-a-kind sorts of Glass Fibre Reinforced Polymer (GFRP) having 3.50 mm thickness were used. Totally five square beams of 3 m duration had been cast. One beam was used as a reference beam and the closing beams had been supplied with GFRP laminates on their soffit. The variable considered for the have a look at is the sort of GFRP laminate. The take a look at parameters of this research protected first crack load, yield load, last load, first crack deflection, yield deflection, closing deflection, crack width, deflection ductility, energy ductility, deflection ductility ratios, and power ductility ratios of the check beams. The overall performance of FRP plated beams became as compared with that of the unplanted beam. The test effects confirmed that the beams reinforced with GFRP laminates exhibited higher performance.
