Análise comparativa do comportamento estrutural entre vigas de aço e vigas mistas de aço e concreto sob aspectos de deformações e de tensões

Abstract

This study aims to perform a comparative analysis between the metallic structural systems and the mixed structural systems of steel and concrete, specifically for the beam elements. The confrontation of the models will occur, mainly, under the behavioral aspects of deformations and the criteria of stress failures. Obtaining data, in order to make comparisons, initially required the elaboration of a hypothetical situation in which the two systems could be applied without the interference of other factors that required the delimitation of a real situation. The process of acquiring this information took place in two stages, first, through the analytical method, consulted in the literature, which made it possible to pre-dimension and choose the metallic and mixed profiles that met the demands of the conjuncture. These were subsequently modeled on the SOLIDWOKS software, which enabled the simulation of parts, which through the numerical method of Finite Elements provides representations of the deformation and stress behaviors very close to that of a physical prototype. In possession of the tabulation of the data provided by the reports presented by the software, it was possible to discuss the performance of the two beam systems presented, seeking to draw routing lines for decision making in structural projects, considering the mechanical behavior of the requesting scenario.
