Abstract

Abstract

Through the experimental research on the shear resistance of BFRP (Basalt Fiber-Reinforced Polylmer) reinforced concrete beams considering recycled aggregate replacement ratio, shear span ratio and reinforcement ratio, the effects of crack propagation, failure mode, replacement ratio of recycled coarse aggregate, shear span ratio and reinforcement ratio of BFRP bars on the shear capacity of the beams were analyzed, and the test results were compared with the four national codes of China, America, Japan and Canda. The results showed that there were two kinds of shear failure of recycled concrete beams reinforced with BFRP bars. Nine test beams were shear-compression damage and two test beams were cable-stayed damage; the deflection of BFRP reinforced concrete beams decreased with the increase of BFRP reinforcement ratio and shear span ratio. When the replacement ratio of recycled coarse aggregate was 30% and 60%, the deflection of BFRP reinforced recycled concrete beams was not significantly different from that of BFRP reinforced ordinary concrete beams. The shear capacity of recycled concrete beams reinforced with BFRP bars was lower than that of ordinary concrete beams reinforced with BFRP bars;at present, the calculation value of ACI 440.1R-15 was the most conservative, and GB 50608-2010 and JSCE 1997 took the second place, while CSA.S 806-12 had better consistency and safety in calculating the shear bearing capacity of recycled concrete beams reinforced with BFRP bars.
