摘　　要：为研究YX75-200-600和YX76-344-688压型钢板-混凝土组合楼板的剪切粘结承载力和剪切粘结性能,进行了18块足尺寸简支压型钢板-混凝土组合楼板的载荷试验,并进行了相关的分析。试验结果表明:18个试件的破坏形态均为剪切粘结破坏,影响剪切粘结性能的主要因素有剪跨、压型钢板厚度和栓钉。由试验数据分析得到的端部有栓钉YX75-200-600压型钢板-混凝土组合楼板的剪切粘结系数m,k为228.12,-0.015,YX76-344-688压型钢板-混凝土组合楼板的剪切粘结系数m,k为246.9,-0.0028。The loading test of 18 full size simply supported profiled steel sheeting-concrete composite slabs and some related analysis were performed in order to study the shear-bond bearing capacity and shear-bond property of the YX75-200-600 and YX76-344-688. The test results showed that the failure modes of 18 specimens were totally shear-bond failure. The influence factors of shear-bond property were span, thickness of profiled steel sheeting and studs. Based on the test results, the shear-bond coefficients m and k of YX75-200-600 profiled steel sheeting-concrete composite slabs were 228. 12 and - 0. 015 respectively. YX76-344-688 profiled steel sheeting-concrete composite slabs were 246. 9 and -0. 0028 respectively.
