| 摘 要： | 通过三根再生混凝土叠合梁和一根再生混凝土整浇梁的抗剪性能对比试验,研究了叠合梁和整浇梁的裂缝发展、破坏形式和抗剪承载力。试验结果表明:再生混凝土叠合梁的抗剪破坏形式和受力机理与整浇普通混凝土梁类似。取代率高的再生混凝土叠合梁抗剪承载力略低于取代率低的再生混凝土整浇梁。

| Abstract: | Tests on three recycled concrete composite beams and one whole cast recycled concrete beam shear performance and comparison were carried out.A study on crack development,failure modes and shear capacity of the beams was developed.The results showed that:recycled concrete composite beam shear failure modes and mechanisms were similar to those of the whole cast ordinary concrete beams.Shear strength of higher replacement ratio of recycled aggregate concrete composite beams were slightly lower than the lower ratio one. |

| Keywords: | recycled aggregate concrete composite beam shear behavior failure mode numerical analysis |
