“…The fiber-reinforced polymer bar, popularly known as FRP bar [31], can be manufactured using uninterrupted fibers enclosed in the polymeric-resin matrix [32]. The main purpose of a fiber is to carry a load, and the resin will act as a binding material [33,34], which transfers this load to fibers [27,28]. Fibers are protected by resin.…”

“…It can be considered a disadvantage of using GFRP bars. Besides, due to low elasticity modulus [28], GFRP-reinforced members display more significant deformations and broader cracks than beams and columns reinforced using steel reinforcement of a similar cross section and area. A helical shape in the bars can enhance the ductility of the FRP-reinforced elements.…”

“…FE model presented in this research also predicted the anchorage failure of FRP-reinforced members at a high temperature which was a typical mode of failure in fire tests discussed in the literature. T. Morgado et al presented a study on GFRP columns embedded in partition walls and building facades making them fire resistant [28]. Frequent retrofitting to maintain corrosion damaged steel-reinforced concrete members can lead to higher maintenance cost [29].…”

Since the nineteenth century, reinforced concrete was evolved as a crucial material for construction. This popular composite material is broadly used in different building typologies. However, the decaying of steel rebar due to corrosion is identified as a hindrance that can affect the quality of reinforced concrete structures. In reference to this, the glass fiber-reinforced polymer (GFRP) bar is essential because of corrosion-resistant properties. The researchers performed various tests and numerical analysis to know the response of GFRP-reinforced flexural members in shear and bending. Based on studies over the last decade, this study critically analyzes the response of flexural member reinforced using glass fiber-reinforced polymer (FRP) bars. Understanding the behavior of the FRP bar as the alternating reinforcing material will be aided by this review. Since the GFRP bar has high strength and no yield point, the conventional characterizations of ductility may not be applicable to determine whether GFRP-reinforced concrete components are ductile. Hence, a detailed study is needed to understand the behavior of such structures. This paper explores various properties of GFRP-reinforced beams to appreciate the applications of GFRP reinforcement in flexural members.

“…It is produced by using ordinary Portland cement (OPC) as a calcium supplier, quartz sand as siliceous material, and fibres for reinforcement. After being moulded by compression, the specimens are subject to autoclaving treatment at a water-saturated steam pressure of 1.0-2.3 MPa (180-220 C) for a certain time [30][31][32][33][34][35].…”
