Abstract(s)
Neste trabalho é realizada a aplicação da parte 3-1 do Eurocódigo 3 no projeto de uma estrutura metálica treliçada de suporte de cabos de energia elétrica. Esta parte do Eurocódigo foca o projeto destas estruturas. Com a elaboração deste documento além da demonstração de aplicação desta parte do Eurocódigo, são realizados apontamentos que demonstram as diferenças de aplicabilidade entre a parte 1-1 e a parte 3-1, sendo, estas diferenças focadas no decurso do desenvolvimento do projeto de uma torre metálica treliçada composta apenas por elementos estruturais.
Para o desenvolvimento do modelo numérico é utilizado o software Robot Structural Analysis da Autodesk, para uma estrutura de base quadrada com 3,43m de lado e com 29,80m de altura, acima do solo, com um quadro estrutural simétrico formado, exclusivamente, por cantoneiras de lados iguais e com uma tipologia estrutural articulada.
Por fim, são analisadas as diferenças supracitadas e retiradas as devidas conclusões e a afetação que estas provocam a nível comportamental e de economicidade.
In this work the application of part 3-1 of the Eurocode is applied to the project of a steel lattice structure supporting electric power cables. This part of the Eurocode focuses on the design of this type of structures (of various typologies). The writing of this document besides demonstrating the application of this part of the Eurocode, contains also notes that show the differences of applicability between part 1-1 and part 3-1, being these differences focused on the course of the development of the project of a steel lattice tower made exclusively of structural elements. The software Robot Structural Analysis of Autodesk is used for the development of a digital model of a square based structure measuring on the side 3,43m and with 29,80m height, above the ground, with a symmetrical structural framework formed exclusively of equal sides angles and with the typology of a truss structure. Finally, the above-mentioned differences are analyzed and conclusions drawn and the impact these have on a behavioral and economy level.
