As estruturas metálicas inserem-se no setor metalomecânico, responsável pela sua projeção e posterior conceção, sendo parte integrante do setor de construção civil. Uma vez que o ramo das estruturas metálicas tem vindo a dominar o setor construtivo, requer-se constante inovação, visando a sua otimização. Este facto prende-se com as características associadas à construção metálica, entre elas, a possibilidade de pré-fabricação em grande escala, a obtenção de áreas livres mais vastas e amplas, a aparência mais esbelta e consequente custo associado reduzido comparativamente às restantes alternativas de construção e, finalmente, de um ponto de vista remetente à sustentabilidade ambiental, a possibilidade de reciclagem do material construtivo, neste caso, o aço. Posto isto, na presente dissertação estudam-se todos os parâmetros de projeto para a análise e dimensionamento de uma estrutura metálica, com base nas normas vigentes, sendo necessário abordar os métodos de estudo, analíticos e computacionais, existentes para o efeito. Para uma análise completa do setor em estudo, é necessária a detenção de conhecimento de todo o processo associado à conceção da estrutura, desde a sua orçamentação, fabrico, transporte e montagem, em consonância com os métodos de gestão e controlo em vigor. Deste modo, reúnem-se todas as condições e pressupostos necessários à correta projeção de uma estrutura metálica (presente no desenvolvimento na dissertação), bem como à gestão de todos os procedimentos abrangentes.
Metal structures are part of the metal-mechanical sector, which is responsible for their project and subsequent realization, and it is an integral part of the construction sector. Because metal structures have been dominating progressively the construction sector, it requires constant innovation, aiming at its optimization. This fact is related to the characteristics associated with metallic construction, including the possibility of large-scale prefabrication, wider free areas, slimmer appearance and, therefore, reduced associated cost, in comparison to other alternatives of construction. Additionally, an advantage associated to this type of construction is related to its environmental sustainability, due to the possibility of recycling the building material, in this case, steel. For this reason, in this dissertation all design parameters for the analysis and design of a metallic structure are studied, based on current standards, and it is necessary to address the analytical and computational methods that exist for this purpose. To achieve a complete analysis of the studied sector, it is necessary to have knowledge of the entire process associated with the design of the structure. For this reason, segments such as, budgeting, manufacturing, transport and assembly, as well as management and control methods, need to be considered in this study. To conclude, all the conditions and assumptions required for the accurate project of a metallic structure (developed in the course of the current dissertation) are met, as well as the management of all comprehensive procedures.
