摘要:
通过新型叠合梁、传统矩形叠合梁及现浇对比梁在单调荷载下的足尺模型试验，对试件梁端的破坏形态、整体受力性能、斜截面抗剪承载力与位移延性等进行了研究。结果表明：新型叠合梁与现浇对比梁均发生了剪切破坏；在受力全过程中，新型叠合梁的裂缝特征和破坏形态都与现浇对比梁类似，没有出现沿叠合面发展的水平裂缝；新型叠合梁的倾斜叠合面上预埋抗剪连接件后能进一步提高试件的整体受力性能；新型叠合梁的抗剪承载力比传统矩形叠合梁提高了约12%，与现浇对比梁相当；新型叠合梁的位移延性系数较现浇对比梁的低9%~13%，比传统矩形叠合梁的高8%~13%；所提出的新型叠合梁与现浇对比梁的整体性能较为接近，可满足工程设计要求。
