The Analysis of Beam Reinforced with FRP Bars in Bending

The paper presents the computational analysis of static behavior of simply supported beam reinforced with FRP (Fiber Reinforced Polymers) bars. The available calculation procedures and design assumptions were listed. The design of FRP reinforcement procedures for flexural strength and long-term deflection according to American (ACI 440.1R-06) guidelines were analyzed. Moreover, the analysis of computations of simply supported beam reinforced with CFRP (Carbon Fiber Reinforced Polymers), AFRP (Aramid Fiber Reinforced Polymers) and GFRP (Glass Fiber Reinforced Polymers) bars based on American guidelines were done and compared. The differences between obtained properties dependent on various types of reinforcement were identified.
