Nowadays several research concerns studying the behavior of FRP reinforcement in different structural members. FRP bars have numerous advantages that make them a good alternative to steel reinforcement, such as superior mechanical properties, non-corrosivity, sustainability, and a relatively higher stiffness-to-weight ratio compared to steel reinforcement. FRP also has good fatigue characteristics, damage tolerance, nonmagnetic properties, simplicity of transportation and handling, and low energy consumption during manufacturing. This paper presents a general review of the behavior of concrete beams reinforced with different types of FRP. The effect of using the different types of FRP reinforcement on the behavior of RC beams has been evaluated in terms of the ultimate capacity, deflection, cracking patterns, etc. In addition, this paper aims to evaluate the efficiency of using some techniques for strengthening reinforced concrete beams such as applying externally bonded CFPR or steel plates on the flexural and shear behavior of the tested beams.
