Theoretical Investigation of Concrete Beams Reinforced with Steel and Fiber Reinforced Polymer Bars

Description
This paper presents a nonlinear finite element model to investigate the behavior of concrete beams reinforced with hybrid Fiber Reinforced Polymer bars and steel reinforcement. Different types of Fiber Reinforced Polymers; CFRP, GFRP and BFRP; were used along with steel rebars in the studied concrete beams. The study was conducted using the nonlinear finite element program ‘‘ANSYS”. For this purpose, research will be carried out on experimental specimens available in the literature prepared with a different cross-section, length, and reinforcement ratios. The study showed that the contribution of steel rebars to FRP reinforced concrete beams improved beam ductility and eliminated the unfavorable brittle failure of the concrete beam. The theoretical results also indicated that the FRP reinforcement was found to play an important role to resist loading after yielding of steel in over reinforced sections.
