Using ABAQUS finite element software,three finite element models are established for honeycomb core hollow floor,cross shaped floor,and multi ribbed floor with the same vertical uniformly distributed load and span,The stress and deflection cloud maps of the three different types of floor under the same state are obtained through force analysis.The results show that when the span of the floor is large,under the same conditions of vertical uniform load and structural self weight,compared to the common cross shaped floor and multi ribbed floor,the honeycomb core hollow floor has a more uniform and reasonable stress distribution;compared with ribbed floor systems,honeycomb core hollow floor systems have greater bending stiffness;compared with the cross shaped floor slab,the honeycomb core hollow floor slab can provide more usable space when the building height is the same.When the net height of the floor is the same,the honeycomb core hollow floor slab can reduce the floor height,thereby saving engineering cost.
