摘　　要：压型钢板-混凝土组合楼板因具有刚度大、延性好、施工方便、经济效益优越等特点,目前在我国得到较广泛的应用。通过对YX65-170-510闭口型镀锌压型钢板-混凝土组合楼板的试验,分析了不同剪跨下,混凝土厚度、压型钢板厚度、楼板高度等因素对组合楼板极限承载力的影响和楼板荷载-挠度关系曲线,对压型钢板和混凝土之间的纵向受剪性能进行了研究,确定了该类型压型钢板-混凝土组合楼板的纵向抗剪承载力计算公式。Recently, the composite floor slab with the profiled steel sheet-concrete has been extensively applied to engineerings because of its big rigidity, good ductility, ease for construction, and good economic returns etc. Through the experiments for the composite floor slabs with the YX65 - 170 - 510 closed profiled steel sheet-concrete, the influence on the ultimate beating capacity of the slabs by the factors of concrete thickness, sheet thickness, slab height and so on under different shear span ratio is analyzed as well as the relation curve of the slab load and deflection. Furthermore, the longitudinal shear-bearing performance between the sheet and concrete is studied to determine the calculation formula for the longitudinal shear-bearing capacity of this slab.
