| Abstract | ||
| Recently, reinforced concrete (RC) structures have been strengthened and rehabilitation flexural using different fiber-reinforced polymer materials in more than technique the primary strengthening methods that researchers have studied, both theoretically and empirically. the first technique is a near-surface mounted (NSM) bar, the subsequent method is using a near-surface mounted (NSM) plate, and the third technique is Externally bonded (EB) sheets using one of the four types of FRP or a combination of them. carbon fiber reinforced polymer (CFRP) in the first, the second using armed fiber reinforced polymer (AFRP), the third using glass fiber reinforced polymer (GFRP), and the last one using basalt fiber reinforced polymer (BFRP) due to that Older buildings need to be maintained and repaired because of their exposure to severe environments, increased applied loads, deterioration of reinforcement from corrosion, damage from design or construction mistakes, and inadequate maintenance. This research intends to give an overview of the literature on the Bending behavior of fiber-reinforced polymer (FRP)enhanced (RC beams) under a variety of approaches; Additionally, Attention was also given to the method of manufacturing, the different types and components of fiber, the mechanical properties, and a comparison of the cost of different strengthening techniques. It sheds light on the methods of retrofitting and its various applications. | ||
