shear contribution of basalt fiber reinforced polymers bars(BFRP) reinforced light weight concrete (FRLWC)

This study evaluates both experimentally and analytically the shear behavior of basalt fiber-reinforced concrete (BFRC) beams reinforced longitudinally with basalt fiber reinforced polymer (BFRP) bars. A new type of basalt macro-fibers was added to the concrete mix to produce the BFRC mix. Fourteen beams were tested under four-point loading configuration until failure occurred. The beams were grouped in two groups A and B depending on their span-to-depthratios. The test results showed that the addition of basalt macro-fibers to the concrete mix enhanced its compressive strength.a new modified model incorporating the type of the longitudinal reinforcement, the type of FRC used, and the density of concrete was proposed. The model of Ashour et al. – A (1992) was calibrated. The proposed model predicted well the shear capacities of the BFRC-BFRP beams. The shear capacities of the lightweight concrete beams tested by Abbadi (2018) were predicted with an average ratio the model predicted well the shear capacities of the SFRC beams reinforced with BFRP bars tested by Awadallah et al. (2014), it is recommendation that the proposed model be assessed on larger set of data than that presented in study the experimental program is presented.
