Basalt fiber-reinforced polymer (BFRP) bars are a new material used in reinforced concrete (RC) structures. They present such properties as high tensile strength, low modulus of elasticity and shear strength. Due to these mechanical properties, flexural behavior of BFRP RC elements is significantly different to that of traditional steel RC. This paper presents the results of an experimental and theoretical study of the short-term flexural behaviour of a series of simply supported BFRP RC beams. The beams were tested under four-point bending. The main objective of this paper was to investigate deflections of the beams depending on reinforcement ratio. The results of experiments were compared with code formulations and prediction models.

Basalt fiber-reinforced polymer (BFRP) bars can be a good alternative to traditional reinforcing steel. This type of reinforcement has low modulus of elasticity, hence deflections and cracking in BFRP RC flexural elements are larger than these found in typical RC members. As a result, the design of FRP RC beams is often governed by the serviceability limit states (SLS). This paper presents chosen results of a research programme in which 6 beams have been tested under four-point bending. The beams were varied in terms of the reinforcement ratio and diameter of rebars. The main goal of this paper was to investigate crack spacing and crack width of the beams. The results of experiments were compared with code formulations.
