Fiber-reinforced polymer (FRP) bars are a relatively new reinforcement material used in civil engineering. This type of reinforcement has low modulus of elasticity and high tensile strength. Hence, the behaviour of FRP reinforced concrete (RC) members is significantly different to that of traditional steel RC. This paper presents the results of numerical and theoretical studies of the flexural behaviour of simply supported basalt fiber-reinforced polymer (BFRP) RC beams under short-term static loads. The numerical analysis was performed using the finite element method (FEM). The main goal of this paper was to investigate deflections and failure mechanisms of BFRP RC members depending on the reinforcement ratio. The results of the numerical analysis were examined and compared with code formulations.
