UM ESTUDO ANALÍTICO-NUMÉRICO DA INFLUÊNCIA DAS CONDIÇÕES DE CONTORNO E DO PROCESSO DE CÁLCULO NA RESPOSTA DE UMA PLACA RETANGULAR NA ZONA DE CONEXÃO COM OS APOIOS

Resumo

In civil construction the slab-beam or slab-pillar connections present some uncertainties in
the analysis of their efforts, which has led to discrepancies between the calculation and the actual
behavior of these structural elements. In addition to inaccuracy during its execution, variations from the
conditions adopted in numerical modeling and the accuracy of the calculation procedures also increase
the divergence between the results of these analyzes and those observed in loco. These elemental
connection zones are critical regions that require this questioning, and thus the results of deflection of a
uniformly loaded plate subjected to six different supporting conditions were analyzed comparatively by:
(a) Finite Differences Method; (b) Finite Element Method using ANSYS software; and (c) analytical
formulation available in the literature. The combinations of support conditions ranged from brimmed to
crimped edges. We also conducted a convergence study of the results for each of the imposed conditions,
noting that some of the analyzed conditions require greater caution from the designer, given the nature
of the analysis methods used and the conditions of the problem addressed.
