摘　　要：为研究压型钢板-混凝土组合楼板的刚度,进行了18块由YX75-200-600和YX76-344-688型压型钢板制作而成的混凝土组合楼板的载荷试验。通过分析试验结果及其受力性能,得到了其荷载-挠度关系曲线的变化规律、受力过程中三个阶段的受力特征、以及中和轴的变化规律;得到了端部栓钉、压型钢板板型及其厚度对刚度的影响规律,从而为该类型组合楼板刚度的理论分析及其工程应用提供试验依据。In order to study the rigidity of profiled steel sheeting-concrete composite slabs,loading tests for eighteen YX75-200-600 and YX76-344-688 cold profiled steel sheeting-concrete composite slabs are carried out.By analyzing the test results and the bearing performance of these specimens,the variation regularity of the load-deflection curves,the stress characteristics of three stages during the loading and the variation of central axis are obtained.Then the influence laws of the studs,the deck shape and thickness of profiled steel sheeting on the rigidity of composite slabs are analyzed,which provide the test foundation for theoretical analysis of rigidity and engineering application of this type of composite slabs.
