However, the analysis and sizing of these pavements require extra attention, due to the complexity of the structural behavior in the connection regions between slab and pillar. In these areas, high bending moments and shear forces are concentrated, which can cause puncture rupture. The inadequate choice of the computational model can lead to substantial errors in the prediction of structural behavior, compromising the safety of the project. In this context, this work compared the results of displacement, support reaction and unbalanced moment in the center and edge pillars referring to three computational models performed by the finite element method. The computational models developed in this study simulated a typical floor slab in smooth reinforced concrete, based on experimental models documented in the technical literature. The first model adopted columns represented by bar elements and slabs by shell elements. The second model followed a similar approach to the pillars in bars, but incorporated a grouping of shell elements with high rigidity in the pillar projection region. The third model used solid elements for the pillars and shell elements for the slabs. The vertical displacements, support reactions and unbalanced moments obtained in the computational models were compared with the experimental results. As a result, the computational models did not influence the support reaction results, nor the moment transfer in internal columns, with all models showing good agreement with the results of Sherif and Dilger (2000). In the transfer of moments of edge slab-pillar connections, the pillar modeled as a bar element obtained greater precision among the other models at the moment of rupture. In addition, the application of the Branson method (1965) together with the computational models obtained excellent results for the vertical displacements in the pillar strip, however, the same did not happen for the internal strip.Acesso AbertoLajes lisasDeslocamento verticalModelagem computacionalPunçãoAnálise linearFlat slabVertical displacementComputational modelingPunching shearLinear analysisCNPQ::ENGENHARIAS::ENGENHARIA CIVIL::ESTRUTURAS::MECANICA DAS ESTRUTURASTrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivs 3.0 Brazil
