in the design. So whereas concrete reinforced with steel would typically be designed to ACI 318, this would not be suitable for GFRP reinforcing bar, which relies on the ACI 440.1R design guide instead. As an example, GFRP reinforcing bar has a higher tensile strength than steel but a lower tensile modulus.
Basalt fiber characterized by high corrosion resistance and relatively low production cost has been increasingly employed in concrete constructions worldwide. However, few studies focused on the flexural performance of basalt fiber reinforced concrete (BFRC) structural members.
