摘　　要：使用ANSYS有限元结构分析软件,针对正六边形蜂窝型空腹夹层板楼盖进行分析。分析影响正六边形蜂窝型空腹夹层板楼盖中划分网格的尺寸效应,对比分析了此种结构与正交正放网格空腹夹层楼盖的网格尺寸与楼盖承载能力之间的效应关系。结果表明,正六边形蜂窝型空腹夹层板的网格尺寸效应比较明显,在合适的网格尺寸下,其钢-混凝土共同作用更加充分,经济效益更加优秀。此外,分析了混凝土表层板厚度对此种结构网格尺寸效应的影响,结果表明,增加混凝土表层板厚度,对于楼盖的承载力有正向增益,同时对结构的网格尺寸效应影响较大。An analysis has been made of the hexagonal honeycomb fasting sandwich sheet covers by using ANSYS finite element structural analysis software.On the basis of the size effect of grid division in the hexagonal honeycomb hollow sandwich panelfloor,a comparative study has been carried out on the effect relationship between the grid size of the fasting sandwich covers and the bearing capacity of the building covers,with the results showing that there is an obvious grid size effect of the regular hexagonal honeycomb fasting sandwich plate,and the steel concrete interaction is more sufficient with more excellent economic benefits.A further analysis has been made of the influence of concrete surface slab thickness on the grid size effect of this structure,with the results showing that an increase of the thickness of concrete surface slab has a positive gain on the bearing capacity of the building cover with a great influence on the grid size effect of the structure.
