Glass Fiber Reinforced Concrete Behavioral Studies in Flexure

Fiber-reinforced polymer (FRP) bars have been commercially available in civil engineering in the last twenty years. Due to their mechanical and physical properties, the behavior of FRP reinforced concrete (RC) members is significantly different to that of traditional steel RC. This paper presents the results and discussion of a numerical study of the flexural behavior of simply supported glass fiber-reinforced polymer (GFRP) RC beams under short-term static loads. The numerical analysis was performed using the Finite Element Method (FEM). All calculations were carried out in the environment of the Abaqus. The main objective of this paper was to investigate the flexural behavior of GFRP RC members depending on the reinforcement ratio. The results of the numerical analysis were examined and compared with code formulations and with the results of experiments.
