摘　　要：通过对不同再生粗骨料取代率的再生混凝土简支梁的抗剪试验,研究了再生混凝土梁的抗剪承载力。试验结果表明:再生混凝土梁的破坏形式和受力机理与普通混凝土梁相似,再生混凝土梁的破坏荷载略低于普通混凝土梁。在试验研究的基础上,提出了再生混凝土梁斜截面抗剪承载力计算公式。This paper mainly discussed the shear capacity of simply-supported beam using recycled concrete with different replacement ratio of recycled coarse aggregate. The test result showed that the failure modes by shear and shear mechanics of recycled aggregate concrete beams were similar to natural aggregate concrete beams＇, but the final failure load was a little lower than that of natural aggregate concrete beams. Based on the result of the test ,the calculation formula of oblique section shear capacity is proposed.
