Abstract(s)
Com o objetivo de realizar um levantamento das principais características, disposições e exigências
dos regulamentos vigentes para estruturas pré-esforçadas o trabalho apresenta uma
comparação entre a norma europeia NP EN 1992-1-1 (2010) (Eurocódigo 2 - Parte 1) e a norma
brasileira NBR 6118 (2014). Assim, será apresentado o dimensionamento de uma viga de
cobertura de uma edificação industrial em betão pré-esforçado de acordo com cada um dos regulamentos.
De maneira geral, foi verificado que ambos os regulamentos apresentam características
muito semelhantes, deixando as diferenças mais evidentes no que diz respeito à caracterização
dos materiais e gerando distinções nos valores de perda de pré-esforço e flechas. Entretanto,
apesar das diferenças ao longo do processo os dois regulamentos apresentaram valores finais
semelhantes para a edificação estudada.
With the purpose to carry out a survey of the main characteristics, provisions and requirements of current regulations for prestressed structures, the work presents a comparison between the European standard NP EN 1992-1-1 (2010) (Eurocode 2 - Part 1) and the Brazilian standard NBR 6118 (2014). Thus, the design of a roof beam of an industrial building in pre-stressed concrete will be presented according to each of the regulations. In general, it was found that both regulations have very similar characteristics, making more evident the differences about the characterization of the materials and generating distinctions in the values of prestress and arrow loss. However, despite the differences throughout the process, the two regulations presented similar final values for the studied building.
