摘　　要：本文通过试验研究了不同取代率的再生混凝土简支梁有箍筋梁的斜截面抗剪性能,试验结果表明,再生混凝土梁的破坏形式基本与普通混凝土梁类似,再生混凝土梁的破坏荷载低于普通混凝土梁,其抗剪承载力随着剪跨比的增加而降低。This paper mainly discussed the shear behavior of simply-supported beam using recycled concrete with different replacement ratio of recycled coarse aggregate.Test results show that the destroy form of recycled concrete beams and stress mechanism and ordinary concrete beam similar to natural aggregate concrete beams＇, and the final failure load was a little lower than that ofnatural aggregate concrete beamst. The shear capacity~ was decreased with the increased of the shear span ratio.

关 键 词：再生混凝土 抗剪承载力 剪跨比 斜向开裂荷载
