Abstract(s)
Neste trabalho é apresentado o processo de concepção de uma estrutura de aço para um galpão de um
supermercado localizado na cidade do Porto, de acordo com as diretrizes do Eurocódigo 3. Com base no
projeto arquitetônico fornecido, inicia-se com a fase de concepção da estrutura de modo que atenda às
demandas do projeto, com foco no dimensionamento da estrutura primária. Essa estrutura consiste em
um pórtico treliçado com vão de 31 metros e altura de 5 metros. Para auxiliar no desenvolvimento do
projeto, utiliza-se o Programa Robot Structural Analysis Professional 2022, um modelador estrutural de
elementos finitos. Nele, são definidas as seções transversais das barras e suas orientações. As forças
atuantes e suas combinações são implementadas no modelo. A partir deste ponto, obtém-se a envoltória
dos esforços internos solicitantes utilizada no posterior dimensionamento da estrutura. São verificadas a
influência dos efeitos de segunda ordem e das cargas térmicas. O objetivo deste estudo é dimensionar a
estrutura primária e realizar uma comparação entre o cálculo manual balizado por uma planilha elaborada
pelo autor e o cálculo automático realizado pelo programa para um elemento estrutural relevante, a fim
de validar os resultados e verificar a funcionalidade do programa. A partir do dimensionamento, chega se a um pórtico utilizando perfis europeus do tipo HEA e SHS, o que possibilita a criação de desenhos em
planta, corte e elevação da estrutura de cobertura do supermercado. Pode-se concluir que o programa é
funcional, prático e de fácil utilização, proporcionando economia significativa do tempo de análise e
confiabilidade dos resultados.
This work presents the design process of a steel structure for a warehouse in a supermarket located in the city of Porto, in accordance with the guidelines of Eurocode 3. Based on the provided architectural design, the design phase begins by conceptualizing the structure to meet the project's demands, with a focus on the primary structure's design. The primary structure is a truss portal frame with a span of 31 meters and a height of 5 meters. The Robot Structural Analysis Professional 2022 software, a structural finite element modeler, is used to assist in the project's development. In this software, the cross-sections and orientations of the bars are defined. The acting forces and their combinations are implemented in the model. From this point, the envelope of the internal solicitation forces is obtained, which is used in the subsequent structural design. The influence of second-order effects and thermal loads is considered. The objective of this study is to design the primary structure and perform a comparison between the manual calculations, based on a spreadsheet developed by the author, and the automatic calculations performed by the software for a relevant structural element, in order to validate the results and verify the program's functionality. Based on the design, a portal frame is achieved using European profiles of the HEA and SHS types, allowing for the creation of plans, sections, and elevations of the supermarket's roof structure. It can be concluded that the program is functional, practical, and user-friendly, providing significant time savings in analysis and reliable results.
