Resumo: | The civil construction industry consumes a large amount of natural resources, generating a lot of waste and being responsible for a considerable part of worldwide environmental impacts. The use of timber in structures in civil and agricultural construction resurfaces as a more acceptable solution considering it’s a renewable material for structures and other building parts. Furthermore, the use of wood in a permanent form contributes with the reduction of carbon emissions in the atmosphere, the objective of the present study was a manufacture and test glulam frames with steel cables to evaluate its application as a structural member in poultry farm building. Four reduced scale glulam frames with 1.9 m spam, 1.83 m column and a 3/8” diameter threaded steel bar as a cable under tension were manufactured. The material used in the frames were wood from the species Pinus sp, and a two-component adhesive based on vegetables oils. The mean ultimate load of the testes frames was about 1.37 times the design load. Furthermore, the displacement development observer in the tests was approximately linear even the loads were high. The value obtained for the Pearson correlation coefficient between the apparent wood density and the frame’s strehngth was 0.95. Finally, the results of the study indicate that the use of a steel cable in the frames improved the mechanical behavior regarding structural strength and stiffness. |

El empleo de la madera en estructuras se muestra como un material ambientalmente correcto en el sector de la construcción civil y agrícola por ser un material constructivo/estructural renovable y su uso de forma permanente contribuye con la reducción de las emisiones de carbono en la atmósfera. Con eso, el presente estudio objetiva ejecutar y ensayar pórticos con tirantes, hechos en madera laminada pegada, a manera de poder calificar su aplicación estructural en aviarios. Fueron confeccionados cuatro pórticos en escala reducida con tirantes de barras de metal con rosca de 3/8", con distancia horizontal libre de 1,9 metros y altura del pilar con 1,83 metros. Los materiales utilizados para la fabricación de los pórticos fueron la madera de Pinus sp. y pegamiento bicomponente con base de aceites vegetales. Las estructuras rompieron para una carga media de 1,37 veces la carga de verificación establecida y mostraron deslocalización próximos a la linearidad mismo con cargas elevadas. Por así, se obtuvo un coeficiente de correlación de 0,95 entre la densidad aparente de la madera de los pórticos con su resistencia. De esta forma, las evidencias obtenidas indican que el empleo de tirantes en la estructura demuestra la mejoría del desempeño mecánico relacionado con la resistencia y rigidez.A indústria da construção civil é uma grande consumidora de recursos naturais, gerando muitos resíduos e sendo responsável por grande parte dos impactos ambientais mundiais. O emprego da madeira em estruturas ressurge como um material ambientalmente correto no setor da construção civil e agrícola por ser um material construtivo/estrutural renovável e seu uso de forma permanente contribui com a redução das emissões de carbono na atmosfera. Com isso, o presente estudo objetivou executar e ensaiar pórticos com tirantes, feitos em madeira laminada colada, de modo a avaliar sua aplicação estrutural em aviários. Foram confeccionados quatro pórticos em escala reduzida com tirantes de barras rosqueadas de 3/8”, com vão livre de 1,9 metros e altura de pilar de 1,83 metros. Os materiais utilizados para a confecção dos pórticos foram a madeira de Pinus sp. e adesivo bicomponente à base de óleos vegetais. As estruturas romperam para uma carga média de 1,37 vezes a carga de verificação estabelecida e exibiram deslocamentos próximos a linearidade mesmo para cargas elevadas. Ainda, obteve-se um coeficiente de correlação de 0,95 entre a densidade aparente da madeira dos pórticos com sua resistência. Desta forma, as evidências obtidas indicam que o emprego do tirante nas estruturas promoveu a melhoria do desempenho mecânico quanto à resistência e rigidez.Research, Society and Development2022-02-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2610910.33448/rsd-v11i2.26109Research, Society and Development; Vol. 11 No. 2; e52711226109Research, Society and Development; Vol. 11 Núm. 2; e52711226109Research, Society and Development; v. 11 n. 2; e527112261092525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/26109/22832Copyright (c) 2022 Desirè Coraça Possa; Alfredo Petrauski; Sandra Maria Ferreira Couri Petrauski; Gustavo Savaris; Rodrigo Aparecido Jordan; Ricardo Lessa Azevedo; Débora Coraça Possa; Victor Hugo Lazzaretti Padilha; Karina Taiza Tomé; Mateus Couri Petrauski; Adolfo lll Echeandia La Torrehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPossa, Desirè CoraçaPetrauski, AlfredoPetrauski, Sandra Maria Ferreira CouriSavaris, GustavoJordan, Rodrigo Aparecido Azevedo, Ricardo Lessa Possa, Débora CoraçaPadilha, Victor Hugo Lazzaretti Tomé, Karina TaizaPetrauski, Mateus CouriLa Torre, Adolfo lll Echeandia2022-02-07T01:42:50Zoai:ojs.pkp.sfu.ca:article/26109Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:44:14.021011Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
