Finite Element Modelling of GFRP Reinforced Concrete T - Beams | Chapter 7 | Research and Developments in Engineering Research Vol. 7

The present study's basic goal is to judge the static load act of internal GFRP-reinforced RC T-beams employing finite material analysis software named ANSYS. Fibre Reinforced Polymer (FRP) composite is defined as a polymer namely reinforced with fibre. It shows a class of materials that fall into a classification referred to as composite fabrics. Fibre reinforced polymers (FRP) are being used widely in the rehabilitation and retrofitting of existent structures as an external support because of their features like high strength to pressure and stiffness to burden ratios, corrosion opposition, light weight and high stamina. In reinforced actual structures like bridges, chimneys, high-rise houses, etc., they are particularly utilised. In place of fortify, FRP reinforcements are now employed in constructions that are mostly erected along the shore or in hostile environments. These reinforcements come in the shape of reinforcing bars. The basic benefit of FRP rebar is its disintegration resistance, light weight, grit and easy give. The FRP rebars are being used worldwide for many constructions including bridge makeups as well, but not well explored by way of its availability. Totally twelfth numbers of specimens were deliberate in this study with variable parameters to a degree type of reinforcements, reinforcements ratio and concrete grade. Modelling of the T- beams were accomplished ANSYS using dependable 65 and link 8 element and the same were resolved under static loading environments. The results obtained from the ANSYS were distinguished with the theoretical and exploratory analysis. Based on the contrasting suitable conclusions and approvals are made in this place research work. It has been experimentally justified that GFRP bars have a lower modulus of elasticity than brace bars. Since GFRP reinforcement has a lower modulus of elasticity than fortify reinforcement, the deflection was best in the GFRP-reinforced examples. Compared to a normal steel supported beam, the GFRP reinforced beam has a better maximum moment bearing skill. According to stress-strain curves, the FRP reinforced beams display fragile behavior before failing. However, concrete condensation is the most common collapse mode. The GFRP supported beam can handle almost as much weight as a rational steel supported beam. In comparison to a normal steel supported beam, the GFRP reinforced beam had a better residual deflection worth.
