A Material nonlinear finite element analysis for the cast-in-place reinforced concrete hollow slab that occurs from initial loading, cracking, yielding to failing is carried on. The cracking load, ultimate load, the displacement rules and the principal stress distribution rules of the hollow slab under the vertical loads are obtained. A Material nonlinear finite element analysis for the single span hollow flat-plate floor is also carried on. The function of the concealed wide-flat beams is definite by analyzing the principal stress distribution diagram. The calculating results verify the theoretical analysis and give some important conclusions which are great useful to improve the constructing of the new flat-plate floor.
