摘　　要：针对钢 混凝土组合楼板叠合面的抗剪强度、连续组合板设计的纵向抗剪强度和剪跨以及端部锚固对板承载力的影响等问题进行了讨论和分析。在组合楼板的承载力设计中 ,应对支座端部的竖向剪力进行叠合面的纵向抗剪强度验算。对于连续组合楼板 ,可采用连续跨中正弯矩区的长度与简支楼板跨度等效的原则进行剪跨计算。The shear bond strength,the longitudinal shear strength and the shear span in design of continuous composite slabs as well as the influence of the end anchorage on the load carrying capacity of the slabs are commented.In design practice of composite slabs with profiled steel sheeting,the vertical shear force at the exterior support should be checked against the shear bond resistance in an empirical formula relating to the test related parameters.In continuous composite slabs,the shear span is determined based on the assumption that the sagging region length of a continuous composite slab equalizes to the full span of a simply support slab.The influence of the end anchorage to the longitudinal shear strength of the slabs can be evaluated based on the suggested formula.
