Fiber reinforced polymer (FRP) bars are frequently used in civil engineering. due to their many benefits, which include excellent weight-to-strength ratio, light weight, ease of handling, electromagnetic neutrality, and lack of rust, as an alternative to reinforcement steel. FRP has also developed into a competitive and cost-effective structural material as production machinery advances and more industries become industrialized. In this study, the flexural presentation of concrete reinforced (RC) beams and fiber-reinforced polymer (FRP) bars after conditioning for 6, 9, and 12 months with simulated saltwater in a wet-dry environment cycling is investigated. This study's goal is to present new developments in the study of FRP-reinforced concrete structures based on current research. Among the subjects covered in this study are the bond presentation of FRP bars' flexural behavior, concrete's compression behavior, and concrete of ductility structures reinforced with FRP bars in recent years all over the world. The two types of FRP bars employed are basalt FRP (BFRP) and steel-FRP composite bars (SFCBs). Steel bars are used as a point of reference. The beams are subjected to a continuous load during conditioning. There are 24 simple-supported rays in all that have been verified.
