For supported on square columns online without beam, its force characteristics of the overall performance of plate bending in two orthogonal directions simultaneously and similarly appears. the Equivalent Frame Method, the structure is flat layers respectively longitudinal and transverse directions, divided into a plurality of longitudinal and transverse beams composed of cross beam system, and pillars form a space frame. In using software analysis SATWE Hollow Flat Slab, due to the floor SATWE software has to consider elastic deformation features, you can adopt a flexible floor unit is more realistic simulation of slab stiffness and deformations.Keywords: cast-in-place reinforced concrete (RC) hollow flat slab；the equivalent frame method of the solid flat slab
