Abstract

In recent years, the construction industry has increasingly included Fibre Reinforced Polymer (FRP) as a means of reinforcing structures. This practise often involves utilising FRP in conjunction with other commonly used construction materials, including wood, steel, and concrete. Fiber-reinforced polymers (FRPs) provide a range of enhanced characteristics, including a high ratio of strength to weight, a high ratio of stiffness to weight, design flexibility, resistance to corrosion, high fatigue strength, and simplicity of application. Several researchers have conducted studies on the application of FRP sheets or plates as bonding materials for concrete beams. The utilisation of adhesive bonded FRPs for the purpose of enhancing structural integrity has been widely recognised as a successful technique applicable to various forms of concrete constructions, including columns, beams, slabs, and walls. The utilisation of Fibre Reinforced Polymer (FRP) materials for the purpose of external reinforcement of pre-existing concrete structures has been on the rise due to its advantageous properties, including non-corrosiveness, non-magnetism, and resistance to a wide range of chemical substances. Previous research has demonstrated that the application of externally bonded glass fiber-reinforced polymers (GFRP) can effectively augment the flexural, shear, and torsional strength of reinforced concrete (RC) beams. The utilisation of flexible glass fibre sheets has been seen to be highly advantageous in enhancing the structural integrity of RC beams. This is mostly due to their adaptable characteristics, simplicity of manipulation and application, as well as their exceptional tensile strength-to-weight ratio and stiffness. The utilisation of FRPs in the restoration of preexisting concrete structures has shown significant and rapid growth in recent years. Numerous studies have demonstrated the effective use of FRP materials for enhancing the structural integrity of concrete beams that exhibit deficiencies in flexural, shear, and torsional capacities. Regrettably, the existing Indian concrete design standards, commonly referred to as IS Codes, do not incorporate any rules pertaining to the reinforcement of structural elements in terms of flexural, shear, and torsional strengthening utilising FRP materials. Due to the lack of design standards, research and industry collaborated to explore and advocate for FRP in structural restoration, notably flexural, shear, and torsional rehabilitation. Carbon, aramid, or glass fibres are mixed with a polymeric matrix like thermosetting resin to make FRP. Fibers are the main load-bearing component of FRP.
