Comparação entre diferentes modelos computacionais para obtenção de esforços e deslocamentos em um radier de fundação com interação solo-estrutura

Abstract

With the advent of the computer and its constant improvement, the velocity and the ability to process information and calculations are gradually increased. Thus, the use of computational models, in several areas of engineering, is able to perform realistic simulations, and it gets relevant results. Therefore, it was conceived a building of reinforced concrete. The foundation element ponders the Winkler theory which considers the soil as an elastic element environment, whose deformations are proportional to the magnitude of acting loads. The simulations were analyzed on two different soils: a moderately compacted area, and a soft sand, with distinct vertical reaction coefficients. Each model was created in Ftool software, Eberick and SAP. It was analyzed the displacements of the nodes of the grid related to all pillars, the moments in the nodes referred to the two pillars, and the moments at the base and top of the three pillars for the two perpendicular axes. The results showed significant results with respect to the grid displacements in the three models. As to the moments in the considered nodes, the values found for Eberick and SAP models are equivalent, however, for the Ftool model it does not seem to converge. The moments in the spans of the pillars, resemble the other moment's analysis, the Eberick and SAP models are equivalent, and the Ftool model is diverging from the others. Considering the above, without further adaptation in the model of portico associated with soil structure in Ftool, So without further adaptation in the model frames associated with soil structure interaction in Ftool, their use for this simulation did not show up properly.
