Abstract

Abstract:

Three-point bending static loading tests were carried out on five test beams to study the effect of basalt fiber fabric-reinforced cementitious matrix （B-FRCM ） on the shear reinforcement effect of reinforced concrete beams. The failure modes of the test beams and the shear contribution of basalt fiber reinforced polymer （BFRP） grids in the process of loading were analyzed， and the test results were compared with the collected calculation models. The results show that the shear capacity of RC beams strengthened with B-FRCM is obviously improved， and the increase amplitude is 24% ~33%. B-FRCM reinforcement can effectively inhibit the development of inclined cracks and delay the occurrence of limit state. In the four existing calculation models， the shear contribution of BFRP grids is overestimated.
