Design of basalt fiber reinforced concrete composite beams
Abstract 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. In this work, constitutive models for the compressive and tensile behavior of BFRC were firstly validated using experimental results. Then, analytical methods for the calculation of the flexural capacity, the moment of inertia of the cracked transformed section, the effective flexural rigidity of steel-reinforced basalt FRC (RBFRC) beams, and concrete-basalt FRC (RC-BFRC) composite beams were proposed. The analytical results indicate that the ultimate moment and maximum deflection at the mid-span under service load agree well with the experimental results, which is meaningful for guiding the design of structural members with BFRC.
