| Abstract | ||
| The most frequent cause of reinforced concrete deterioration is corrosion of the steel reinforcement, especially in harsh weather. One of the promising materials for structural applications is fiber-reinforced polymer (FRP) material because of its non-corrosive nature. One of the most productions of FRP material is FRP bars which are used in reinforced concrete structures. FRP bars have many advantages such as high strength to weight ratio. This research aims to evaluate the ultimate capacity of reinforced concrete beams with FRP bars by using available specimens in the literature against Eurocode 2 (EC2) specifications and compared with ACI-440.1R-06 code. The results showed that EC2 code overestimates the ultimate moment capacity for 5 samples only (4% of the examined specimens) for normal strength concrete, while EC2 code overestimates the ultimate moment capacity for 16 samples (14% of the examined specimens) for high strength concrete. Therefore, EC2 is more conservative for predicting moment capacity of reinforced concrete beams with FRP bars for normal strength concrete than high strength concrete. On the other hands, ACI 440.1R-06 underestimated the ultimate moment of all concrete beams reinforced with FRP bars. Accordingly, ACI 440.1R-06 is more conservative for predicting moment capacity than EC2. | ||
