Abstract
The goal of this experimental investigation is to test and analyse the shear capacity of spirally reinforced concrete (RC) beams enhanced outwardly using Glass fibre reinforced polymer (GFRP) laminates with partial substitution of coarse aggregate. Over the last several years, substantial study has been undertaken in the field of Construction on the practice of Fibre Reinforced Polymer (FRP) composite materials in the retrofitting of concrete members. The FRP is placed on the webof a component with fibres aligned crosswise to the beam horizontal component for shear strengthening. Shear force resistance is obtained in the same way as embedded steel stirrups are produced: by mending shear fractures that occur beneath effective loads. GFRP may be used in a variety of ways throughout this work, based on the revealed sides of the component and the amount of strengthening sought, such as U-wraps and X-wraps in the shear zone. Environmental features are progressively being used to evaluate building material. Cementitious regeneration is becoming more popular as a means of resource conservation and eliminating necessity dumping by repurposing easily obtainable concrete as a way of adding for new concrete or other purposes. The states that really do employ recycled concrete aggregate (RCA) in fresh concrete indicate that it outperforms similarly to natural aggregate concrete. As a result, RCA is supplanted by 10% to 50%. In comparison to notional shear reinforcement, continuous spiral reinforcement of 45° was utilised as shear reinforcement to prevent shear fracturing. The load capacity, as well as its fracture formations, load deflection behaviour, and stiffness characteristics, were investigated in an actual experiment. The results of the experiment indicated that spirally reinforced concrete beams raised the maximum load much more than control beams. Furthermore, an RC beam with RCA performed better than the control beams. Additionally, spirally RC beams retrofittedwith GFRP outperformed all other forms of beams evaluated.
