Elaboração de um projeto estrutural em concreto armado através de software comercial e comparação com determinados elementos estruturais dimensionados através de métodos semi-automáticos

Abstract

The great technological advances that have occurred in the 21st century have led to changes in the way of designing reinforced concrete structures. The objective of this paper is to present the elaboration of the structural project of a building using the TQS software and also the dimensioning of certain structural elements of this same building by semi-automatic methods, for the purpose of comparing steel areas. A plan presented in the book “Cálculo e detalhamento de estruturas usuais em concreto armado segundo a NBR 6118:2014, 4° edição” by the authors Roberto Chust Carvalho and Jasson Rodrigues de Figueiredo Filho was used as the basis for the building to be designed. It was obtained the result that, for this study, the projects presented differences. The discrepancy between these projects is mainly due to the difference in the calculation models. While the TQS uses the analogy of the grids for dimensioning the pavements and treats the structure as a frame of beams and columns, the semi-automatic method relies on the theory of plates for calculating slabs and considers the dimensioning of each element independently. It was also possible to conclude that for slabs that have loads coming from masonry on it, the TQS tends to present more satisfactory results, that in this case are those that meet the requests, but with less material consumption.
