摘　　要：压型钢板-混凝土组合楼板因其具有刚度大、延性好、施工方便、经济效益优越等特点,目前在我国得到较为广泛的应用。通过对3种共27块(2W、3W、BONDECK各9块,2W、3W为开口板,BONDECK为缩口板)镀锌压型钢板-混凝土组合楼板的试验研究,分析了不同剪跨下,混凝土强度、压型钢板厚度、组合楼板厚度等因素对组合楼板极限承载力的影响,总结了压型钢板-混凝土组合楼板剪切-粘结破坏的形态及受力变形性能,利用回归分析提出了以混凝土抗拉强度特征值ft表征的剪切-粘结承载力计算公式。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 constru-dtion, and good economic retums etc. Through the experiments for the 3 kinds of composite floor slabs total 27 profiled steel sheet-concretes, the influence on the ultimate beating capacity of the slabs by the fac- tors of concrete thickness , sheet thickness , slab height and so on under different shear span ratio is analyzed. Proposed the calculation formula of shear-bond beating capacity bythrough regressive analysis method was proposed and coefficients for this steel plate.
