Resumo: | Reinforced concrete structures are subject to several forms of deterioration, the main one being the corrosion of the metallic reinforcement that causes social and economic damages, especially in regions with high environmental aggressiveness. Therefore, several countries have studied the feasibility of using non-metallic reinforcement, such as fiber reinforced polymers (FRP). In this context, the present work carried out a theoretical and numerical study of the behavior of concrete beams reinforced with glass fiber reinforced polymer bars (GFRP), carbon (CFRP) and aramid (AFRP), in comparison with a reinforced concrete beam. with steel bars. For the same load, the concrete beam with steel bars was designed according to ABNT NBR 6118:2014, and the reinforced concrete beams with FRP bars according to ACI 440.1R:2015. Then, they were numerically simulated in the ANSYS® software to analyze the stresses, strains and displacements. Finally, it was found that the beam with steel bars required a lower useful design height and the beam with CFRP bars required a smaller area of flexural reinforcement. In numerical simulations, all beams showed consistent behavior according to ABNT NBR 6118:2014 and ACI 318:2011, with the beam composed of concrete and steel showing superior numerical responses in relation to the others. In general, the beams reinforced with FRP obtained satisfactory results compared to the beam reinforced with steel bars, where the beam reinforced with CFRP achieved the best results among the beams with fiber reinforced polymer bars. |

Por lo tanto, varios países han estudiado la viabilidad de utilizar refuerzos no metálicos, como los polímeros reforzados con fibra (PRF). En este contexto, el presente trabajo realizó un estudio teórico y numérico del comportamiento de vigas de hormigón armado con barras de polímero reforzado con fibra de vidrio (PRFV), carbono (PRFC) y aramida (PRFA), en comparación con una viga de hormigón armado con barras de acero. Para la misma carga, la viga de hormigón con barras de acero fue diseñada según la ABNT NBR 6118:2014, y las vigas de hormigón armado con barras de PRFV según la ACI 440.1R:2015. Luego, fueron simulados numéricamente en el software ANSYS® para analizar los esfuerzos, deformaciones y desplazamientos. Finalmente, se encontró que la viga con barras de acero requirió menor altura útil de diseño y la viga con barras de PRFC requirió menor área de refuerzo a flexión. En las simulaciones numéricas, todas las vigas mostraron comportamiento consistente según ABNT NBR 6118:2014 y ACI 318:2011, siendo la viga compuesta de hormigón y acero mostrando respuestas numéricas superiores en relación a las demás. En general, las vigas reforzadas con PRF obtuvieron resultados satisfactorios en comparación con la viga reforzada con barras de acero, donde la viga reforzada con PRFC logró los mejores resultados entre las vigas con barras de polímero reforzado con fibras.Estruturas de concreto armado estão sujeitas à diversas formas de deterioração, sendo a principal delas a corrosão da armadura metálica que causam prejuízos sociais e econômicos, especialmente em regiões com alta agressividade ambiental.

Nesse âmbito, o presente trabalho realizou um estudo teórico e numérico do comportamento de vigas de concreto armadas com barras de polímeros reforçados com fibras de vidro (PRFV), carbono (PRFC) e aramida (PRFA), em comparação com uma viga de concreto armada com barras de aço. Para um mesmo carregamento foi dimensionado a viga de concreto com barras de aço conforme a ABNT NBR 6118:2014, e as vigas de concreto armado com barras de PRF segundo o ACI 440.1R:2015. Em seguida, as mesmas foram simuladas numericamente no software ANSYS® para analisar as tensões, deformações e deslocamentos. Por fim, verificou-se que a viga com barras de aço demandou uma menor altura útil de projeto e a viga com barras de PRFC requisitou uma menor área de armaduras de combate à flexão. Nas simulações numéricas, todas as vigas apresentaram comportamento coerente de acordo com a ABNT NBR 6118:2014 e ACI 318:2011, tendo a viga composta por concreto e aço exibido respostas numéricas superiores em relação às demais. Em geral, as vigas armadas com PRF obtiveram resultados satisfatórios em comparação com a viga armada com barras de aço, onde a viga armada com PRFC atingiu os melhores resultados entre as vigas com barras de polímeros reforçados com fibras.Research, Society and Development2022-10-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3486310.33448/rsd-v11i13.34863Research, Society and Development; Vol. 11 No. 13; e177111334863Research, Society and Development; Vol. 11 Núm. 13; e177111334863Research, Society and Development; v. 11 n. 13; e1771113348632525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/34863/29602Copyright (c) 2022 Denn’s Santana Perônica; Héllykan Berliet dos Santos Monteiro; Daniel Nelson Maciel; Rodrigo Barros; Joel Araújo do Nascimento Neto; José Neres da Silva Filhohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPerônica, Denn’s Santana Monteiro, Héllykan Berliet dos Santos Maciel, Daniel Nelson Barros, RodrigoNascimento Neto, Joel Araújo do Silva Filho, José Neres da 2022-10-17T13:43:46Zoai:ojs.pkp.sfu.ca:article/34863Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:49:59.572762Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
