Abstract(s)
Em diversos países, nomeadamente em Portugal, a expansão do mercado da construção metálica tem crescido de forma significativa, principalmente no sector da construção de pavilhões industriais.
Neste projeto, começou-se pelo estudo das diversas soluções estruturais existentes, fazendo-se referência às diferentes tipologias estruturais de pavilhões metálicos com a respetiva descrição dos elementos principais e secundários utilizados nestas construções. Abordou-se também formas de evitar problemas relacionados com o dimensionamento destas estruturas, nomeadamente em relação a formas de travamento de madres, travessas e pilares.
Fez-se um estudo dos métodos e modelos de análise previstos no EC3 e de todo o processo de dimensionamento, face aos diversos fenómenos de instabilidade a que as estruturas metálicas estão sujeitas.
Por fim, realizou-se o dimensionamento de um pavilhão industrial de grandes dimensões (180x30x6 metros), com recurso às metodologias do Eurocódigo 3. Para isso foram definidos diversos modelos de cálculo (2D e 3D). Todo o cálculo foi sustentado pelo programa de cálculo automático Robot Structural Analysis da Autodesk.

In this thesis, it started by studying various existing structural solutions, by making reference to the different structural types of metal pavilions with its description of the main and secondary elements used in these buildings. It also addressed ways to avoid problems related to the design of these structures, particularly in relation to forms of wombs locking, bars and pillars. There was a study of analytical methods and models set out in EC3 and the entire design process, given the diverse phenomena of instability that the metal structures are subjected. Finally, there was the design of an industrial building (180x30x6 meters) using the methodologies of Eurocode 3. For that, we defined much calculation (2D and 3D). All the calculation was supported by the computer program Autodesk Robot Structural Analysis.
