Resumo: The use of prestressed as a solution for steel structures has been proposed since the 1950s and, despite several published studies, is not yet widespread in the professional environment. Its application is made externally to the structure and, among its applications, it is recommended for rehabilitation and reinforcement. Its executive method is relatively simplified, since little changes from the executive procedures of passive steel structures and prestressed concrete. This work aims to analyze the behavior of a rehabilitated steel beam when submitted to the stages of prestressed. For this, tendons will be applied, causing bending also in the direction of less inertia of the structural element. According to the proposed model, it can be observed that the efforts present in the executive stage do not exceed the supporting capacity of the element. However, certain loading phases can cause instability if they are not checked correctly.

Su aplicación se realiza fuera de la estructura y, entre sus aplicaciones, se recomienda para rehabilitación y refuerzo. Su método ejecutivo está relativamente simplificado, ya que se producen pequeños cambios en los procedimientos ejecutivos de las estructuras pasivas de acero y el hormigón pretensado. Este trabajo tiene como objetivo analizar el comportamiento de una viga de acero rehabilitada frente a escalones de pretensado. Para ello, se aplicarán cuerdas, provocando flexión también en la dirección de menor inercia del elemento estructural. De acuerdo con el modelo propuesto, se puede observar que los esfuerzos presentes en la etapa ejecutiva no superan la capacidad de soporte del elemento. Sin embargo, determinadas fases de carga pueden provocar inestabilidad si no se controlan correctamente.A utilização da protensão como solução para estruturas de aço foi proposta desde a década de 1950 e, apesar de diversos estudos publicados, ainda não está difundida no meio profissional. A sua aplicação é feita de forma externa à estrutura e, entre suas aplicações, é recomendada para reabilitação e reforço. Seu método executivo é relativamente simplificado, uma vez que pouco se altera dos procedimentos executivos das estruturas de aço passivas e do concreto protendido. Este trabalho tem como objetivo analisar o comportamento de uma viga de aço reabilitada quando submetida às etapas de protensão. Para isso, serão aplicadas cordoalhas, causando flexão também no sentido de menor inércia do elemento estrutural. De acordo com o modelo proposto, pode-se observar que os esforços presentes na etapa executiva não superam a capacidade de suporte do elemento. Entretanto, determinadas fases de carregamento podem causar instabilidade caso não sejam verificadas corretamente.   Universidade Federal de Viçosa - UFV2021-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1194110.18540/jcecvl7iss1pp11941-01-09eThe Journal of Engineering and Exact Sciences; Vol. 7 No. 1 (2021); 11941-01-09eThe Journal of Engineering and Exact Sciences; Vol. 7 Núm. 1 (2021); 11941-01-09eThe Journal of Engineering and Exact Sciences; v. 7 n. 1 (2021); 11941-01-09e2527-1075reponame:Revista de Engenharia Química e Químicainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/jcec/article/view/11941/6497Copyright (c) 2021 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessJardim, Pedro Ignácio Lima GadêlhaSilva, Benjamim Nogueira daRibeiro, Lívia Maria PalácioAlmeida, Diego Henrique de2021-05-31T12:54:32Zoai:ojs.periodicos.ufv.br:article/11941Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/indexONGhttps://periodicos.ufv.br/jcec/oaijcec.journal@ufv.br||req2@ufv.br2446-94162446-9416opendoar:2021-05-31T12:54:32Revista de Engenharia Química e Química - Universidade Federal de Viçosa (UFV)false
