Resumo: | The road modal stands out as the most used system in Brazil for cargo transportation and people. Thus, it is extremely important to ensure resources for the maintenance of highways and their Special Engineering Structures - SES (bridges, viaducts and pedestrian walkways). The latter, which are the object of this study, play an indispensable role for the safety and comfort of users who cross the highways. However, it is possible to verify that a considerable number of these structures are in very poor conservation conditions, either due to the deterioration that occurs over time, structural deficiencies resulting from vehicle collisions, vandalism, or other factors that affect their useful life. In this sense, this paper aims to estimate the service life of two concrete footbridges located on federal highway BR-101/PE, by applying the concept of service life established by ISO 15686 (2011), NBR 15575-1 (ABNT, 2021) e NBR 15575-2 (ABNT, 2013). For this purpose, data obtained from the DNIT's Special Structures Management System (SGO) were used. The information on the anomalies and the respective structural stability conditions enabled the use of the Factor Method to obtain the estimated and residual service life of the studied works. The results obtained showed that the methodology can be employed in case studies in which there is no history of regular inspections of SES. |

Por lo tanto, es extremadamente importante asegurar los recursos para el mantenimiento de las autopistas y sus Estructuras Artísticas Especiales - EAE (puentes, viaductos y pasos elevados para peatones). Estos últimos, que son el objeto de este estudio, desempeñan un papel indispensable para la seguridad y la comodidad de los usuarios que cruzan las carreteras. Sin embargo, es posible comprobar que un número considerable de estas estructuras se encuentran en muy mal estado de conservación, ya sea por la acción del deterioro que se produce con el paso del tiempo, por deficiencias estructurales derivadas del choque de vehículos, por vandalismo, o por otros factores que afectan a su vida útil. En este sentido, este trabajo tiene como objetivo estimar la vida útil de dos pasarelas de hormigón situadas en la carretera federal BR-101/PE, aplicando el concepto de vida útil establecido por las normas ISO 15686 (2011), NBR 15575-1 (ABNT, 2021) y NBR 15575-2 (ABNT, 2013). Para ello, se utilizaron los datos obtenidos del Sistema de Gestión de Obras de Arte Especiales (SGO) del DNIT. La información de las anomalías y las respectivas condiciones de estabilidad estructural permitieron utilizar el Método de los Factores para obtener la vida útil estimada y residual de las obras estudiadas. Los resultados obtenidos mostraron que la metodología puede emplearse en estudios de casos en los que no hay antecedentes de inspecciones periódicas de EAE.O modal rodoviário se destaca como o sistema mais utilizado no Brasil para o transporte de cargas e de pessoas. Dessa forma, é extremamente importante assegurar recursos que visem à manutenção das rodovias e de suas Obras de Arte Especiais - OAEs (pontes, viadutos e passarelas de pedestres). Estas últimas, que constituem o objeto deste estudo, desempenham um papel indispensável para a segurança e o conforto dos usuários que realizam a travessia das rodovias. Entretanto, é possível verificar que considerável quantidade dessas estruturas se encontra em péssimas condições de conservação, seja pela ação da deterioração que ocorre ao longo do tempo, por deficiências estruturais provenientes do choque de veículos, por vandalismo, ou outros fatores que afetam a sua vida útil. Nesse sentido, este trabalho tem como objetivo estimar a vida útil de duas passarelas de concreto situadas na rodovia federal BR-101/PE, por meio da aplicação do conceito de vida útil estabelecido pelas normas ISO 15686 (2011) e NBR 15575-1 (ABNT, 2021) e NBR 15575-2 (ABNT, 2013). Para tanto, foram utilizados os dados obtidos pelo Sistema de Gerenciamento de Obras de Arte Especiais (SGO) do DNIT. As informações das anomalias e das respectivas condições de estabilidade estrutural possibilitaram a utilização do Método dos Fatores para a obtenção da vida útil estimada e residual das obras estudadas. Os resultados obtidos mostraram que a metodologia pode ser empregada em estudos de casos nos quais não existam um histórico de inspeções regulares de OAEs.Research, Society and Development2021-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2078110.33448/rsd-v10i12.20781Research, Society and Development; Vol. 10 No. 12; e559101220781Research, Society and Development; Vol. 10 Núm. 12; e559101220781Research, Society and Development; v. 10 n. 12; e5591012207812525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/20781/18550Copyright (c) 2021 Clayton José Gomes Silva; José Afonso Pereira Vitório; Maria Helena Melo Ferrer de Morais; Arnaldo Manoel Pereira Carneiro; Romilde Almeida de Oliveirahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Clayton José GomesVitório, José Afonso Pereira Morais, Maria Helena Melo Ferrer deCarneiro, Arnaldo Manoel Pereira Oliveira, Romilde Almeida de2021-11-14T20:26:51Zoai:ojs.pkp.sfu.ca:article/20781Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:40:19.706104Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
