The use of glass fiber reinforced polymers (GFRP) rebars as internal concrete reinforcement had gained a lot of interest worldwide and rapidly increased within the past few years because of several good physical and mechanical characteristics. These materials had a linear stress-strain response up until failure, a high tensile strength, and a low modulus of elasticity. Understanding the flexural behavior of concrete beams reinforced with GFRP bars will provide essential information for the continued use of deformed GFRP bars as internal reinforcement for concrete constructions. A list of available procedures for calculation and design assumptions were provided. This paper includes the most important conclusions from previous studies.
