Estudo Qualitativo do Comportamento de Estruturas de Aço com Foco no Método dos Estados Limites

Abstract

The present work has an qualitative survey of the main limit states that steel structures are subject. First it‟s done an study about the most important project philosophies along the years and about the structural element classification that is used in this work. The limit states are individually studied, with specific topics for each one of them, explaining the behavior of the structural element in consideration of such limit state and, when necessary to the comprehension, quoting the current standards about the theme. The first topics talk about the limit states that needs to be considered in a general way, independent of the type of the structure. The next topics talk about the limit states that occurs in linear elements, subjected to different stresses. Next, bidimensional elements are studied. Finally, the limit states that occurs in elements of bolted and welded connections are studied. In a general way, the failure modes studied are the ones that are commonly included in the textbooks of design of steel structures. The topics studied are then grouped into a diagram, which summarizes the conditions that lead to each of the ultimate and service limit states that commonly occur in steel structures.
