Tóm tắt: | In Brazil, despite the skilled labor shortage, the use of metal structures in buildings has increased considerably due to factors such as speed of execution, cleaning the construction site, low deadweight compared with reinforced concrete structures, low material waste, etc. For better utilization of equipment and for which continuity of the openings is necessary to use the amendments, which can be welded or screwed. The quality of the amendments must meet the standards required by the design standards, in rolled profiles, according to ABNT NBR 8800:2008 (Steel Structures Design and Composite Structures of Steel and concrete buildings). These profiles have great applicability in large structures and their use is growing in buildings with these characteristics. This paper presents the experimental study of bearing capacity of two beams supported by steel made of rolled profiles section I of type W 250 x 22,3 ASTM A-572, grade 50, rolled parallel flaps with two axes of symmetry, being provided splices using full penetration welds MIG type (Metal Inert Gas). Seven beams were tested with a length of 3000 mm, with a reference beam. In the remaining six beams amendments were made in different positions varying the amount of amendments. This study also provides a comparison between the results obtained in this work and those obtained by Pereira (2014), which used beams with bolted connections using the same provisions of the amendments of this work, but with ASTM A-325 and screw diameter of 19 mm. All models have been requested by simple bending stress at break, according to the analysis of vertical displacement, and torsional displacement relative specific deformations steel. The connections of beams resisted the simple bending tests not being observed no break in welds. The main contribution of this work was to show that, if well executed, welded connections and bolted performed by Pereira (2014), with the specifications described in this paper, can be used as elements of connections in steel beams subjected to bending, as well resisted the requested efforts . |

This paper presents the experimental study of bearing capacity of two beams supported by steel made of rolled profiles section I of type W 250 x 22,3 ASTM A-572, grade 50, rolled parallel flaps with two axes of symmetry, being provided splices using full penetration welds MIG type (Metal Inert Gas).

This study also provides a comparison between the results obtained in this work and those obtained by Pereira (2014), which used beams with bolted connections using the same provisions of the amendments of this work, but with ASTM A-325 and screw diameter of 19 mm. All models have been requested by simple bending stress at break, according to the analysis of vertical displacement, and torsional displacement relative specific deformations steel. The connections of beams resisted the simple bending tests not being observed no break in welds. The main contribution of this work was to show that, if well executed, welded connections and bolted performed by Pereira (2014), with the specifications described in this paper, can be used as elements of connections in steel beams subjected to bending, as well resisted the requested efforts .No Brasil, apesar da escassez de mão de obra qualificada, a utilização de estruturas metálicas nas edificações vem aumentando consideravelmente devido a alguns fatores como rapidez de execução, limpeza do canteiro de obras, baixo peso próprio se comparado com as estruturas de concreto armado, baixo desperdício de material etc.. Para o melhor aproveitamento de material e para que se continuidade dos vãos é necessário a utilização das emendas, que podem ser soldadas ou parafusadas. A qualidade das emendas deve atender aos padrões exigidos pelas normas de projeto, no caso dos perfis laminados, segundo a ABNT NBR 8800:2008 (Projeto de Estruturas de Aço e de Estruturas Mistas de Aço e Concreto de Edifícios). Esses perfis tem grande aplicabilidade em estruturas de grande porte e seu uso é crescente em edificações com essas características. Este trabalho apresenta o estudo experimental da capacidade resistente de vigas bi-apoiadas em aço constituídas de perfis laminados de seção I do tipo W 250 x 22,3 ASTM A-572, grau 50, laminados de abas paralelas com dois eixos de simetria, sendo dotadas de emendas com soldas de penetração total do tipo MIG (Metal Inert Gas). Foram ensaiadas sete vigas com comprimento de 3000 mm, sendo uma viga de referência. Nas seis vigas restantes foram confeccionadas emendas em diferentes posições variando a quantidade de emendas. O presente estudo traz também uma comparação entre os resultados obtidos neste trabalho e os obtidos por Pereira (2014), no qual utilizou vigas com ligações parafusadas utilizando as mesmas disposições das emendas deste trabalho, mas com parafusos ASTM A-325 e diâmetro de 19 mm. Todos os modelos estiveram solicitados por esforços de flexão simples até à ruptura, de acordo com a análise dos deslocamentos verticais, deslocamentos relativos à torção e as deformações específicas do aço. As ligações das vigas resistiram aos ensaios de flexão simples, não sendo constatada nenhuma ruptura nas soldas. A principal contribuição deste trabalho foi mostrar que, se bem executadas, as ligações soldadas e as parafusadas realizadas por Pereira (2014), com as especificações descritas neste trabalho, podem ser utilizadas como elementos de ligações em vigas metálicas submetidas à flexão, pois resistiram bem aos esforços solicitados.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESapplication/pdfporUniversidade Federal de GoiásPrograma de Pós-graduação em Engenharia Civil (EEC)UFGBrasilEscola de Engenharia Civil - EEC (RG)http://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessVigaAçoLigações soldadasLigações parafusadasPerfil laminadoFlexão simplesBeamSteelWelded jointsBolted connectionsLaminate profileSimple bendingENGENHARIA CIVIL::ESTRUTURASENGENHARIAS::ENGENHARIA CIVILAnálise experimental da resistência à flexão simples de vigas de aço tipo "I" compostas de perfis laminados dotadas de emendas soldadasExperimental analysis of flexural simple steel beams type "I" com-folded profiles equipped rolled welded amendmentsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesis-65364464898176751756006006006006007240872516263155857962414133013518621-62748332150463957722075167498588264571reponame:Repositório Institucional da UFGinstname:Universidade Federal de Goiás (UFG)instacron:UFGORIGINALDissertação - Rone Sérgio Freitas Borges - 2015.pdfDissertação - Rone Sérgio Freitas Borges - 2015.pdfapplication/pdf6213430http://repositorio.bc.ufg.br/tede/bitstreams/58d6d294-502f-4eb3-9195-eb326ce730d4/download42046e4b45c71b2cd44ac6a2ea27e1bcMD55LICENSElicense.txtlicense.txttext/plain;
