Análise da influência da adoção de vigas contínuas em diferentes métodos de dimensionamento : vigas de aço isoladas e vigas mistas de aço e concreto

Abstract

The present work shows an analysis of the influence of adopting continuous beams in the design of three different structural solutions: steel beams with solid concrete slabs, steel-concrete composite beams with solid concrete slabs and steel-concrete composite beams with composite slabs (steel deck). With this objective in mind, the design of two floors with different dimensions was made, with the help from Microsoft Office Excel spreadsheets and, next, a budget of the necessary inputs for the construction was developed. In possession of these values, it was made the comparative analysis with the results from the work of SANDES (2019), whose research calculated the same floors and the same structural solutions for the simply supported beams conjuncture. Thus, it was determined that the use of continuous beams prompt a significant reduction of the cross section, providing a lesser use of materials and the structure’s weight. It was also made a comparison between the results of the three structural options, concluding that the steel-concrete composite beams with composite slabs solution is the most economic and creates the structure with the least total weight.
