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.
