In order to study the shear capacity of basalt fiber reinforced polymer reinforced recycled concrete deep beam without web reinforcement,9 deep beams under 4 point bending test were conducted.The failure process and failure mode of the tested beam were analyzed.The relationship of shear strength among the shear span ratio,reinforcement ratio of BFRP rebar and the compressive strength of recycled concrete was also discussed,respectively.A formula based on Canadian specification and data fitting for calculating the shearing capacity of the specimens was proposed.Results showed that the main failure mode of BFRP reinforced recycled concrete deep beam without web reinforcement was the shear failure and with the increase of shear span ratio,the shear failure transforms to flexural-shear failure.The shear capacity of experimental beams decreased with the increase of the shear span ratio,while increased with the increase of the reinforcement ratio of BFRP reinforcement and compressive strength of recycled concrete.The predicted results of the adopted calculation model fitted well with the test results and had a certain degree of safety.
