This paper studies the modeling of symmetric and asymmetric flat slabs, presenting alternatives to the problem of singularity encountered when the slab is modeled considering columns as local support. A model that includes the integrated slab x column analysis was proposed, distributing the column reactions under the slab. The procedure used transforms the bending moment and column axial force in a distributed load, which will be applied to the slab in the opposite direction of gravitational loads. Thus, the bending moment diagram gets smooth in the punching region with a considerable reduction of values, being very little sensible to the variation of used mesh.
About the column, it was not seen any significant difference in the axial force, although the same haven't occurred with the bending moments results. The final part of the work uses geoprocessing programs for a three-dimensional view of bending moments, allowing a new comprehension the behavior of these internal forces in the entire slab.

The literature study reviews the analysis of concrete plate type structures using traditional and finite element methods and highlights the difference between linear and non-linear finite element analysis.

Analyses of this type of slab are complex and are often designed using software developed for linear analysis based on the classic plate theory, using numerical analyses (SKORPEN ET AL ). The Finite Element Method (FEM) and Grid Analogy Method are examples for numerical analyses, both procedures widely used by technical designers. The use of numerical models that simulate the slabs-columns connections as being pinned support (singularities) provide results with high concentration of strains across these areas, resulting in peak of bending moments in the slab and distortions of the values of bending moments columns. Results of this type require a more refined analysis to be used in structural designs. According CHOI ET AL, the structural behavior of the slab- columns connections is very complicated, since they are composed of two different types of elements: beams (columns) and plates (slabs). It is known that the slabs-columns connections are not punctual.
