Resumo: | Structure is designed to have satisfactory performance given the quality standards and requirements in the construction of which designers need. Increasingly, large metal structures are developing in this competitive market, where performance and quality of the project depend on manufacturing processes of materials, assembly, inspection and maintenance. The metal structures, especially those of type I profiles of parallel laminated tabs depend on the quality control in your bolted splices. This study aimed to analyze the bearing capacity of steel beams supported by profiles consist of type I rolled parallel flanges with two axes of symmetry, being endowed with seams with high strength bolts type ASTM A325, diameter 19 mm. Eight beams with a length of 3000 mm, two reference beams were tested. In the remaining six beams splices were made at different positions varying the amount of seams. All models have been efforts required by simple bending to failure, by analyzing the vertical displacement, torsional displacement relative and specific deformations of steel. The connections of the beams withstood the test flexural not being observed and no break on the bolts or the connecting plate, featuring breaking loads between 74% and 85% for beams of series with connections. Considerably beams with connections showed no breaking loads far below the reference beams with breaking loads between 78% and 100%. The results indicate that the beams with bolted with high strength bolts connections are sturdy and therefore can be used by designers in the field of steel structure as another option. |

Cada vez mais as estruturas metálicas de grande porte vêm se desenvolvendo nesse mercado competitivo, onde o desempenho e a qualidade do projeto dependem dos processos de fabricação dos materiais utilizados, da montagem, da inspeção e manutenção. As estruturas metálicas, principalmente as de perfis tipo I laminados de abas paralelas dependem do controle de qualidade em suas emendas parafusadas. Este estudo teve por objetivo analisar a capacidade resistente de vigas bi apoiadas em aço constituídas de perfis tipo I laminados de abas paralelas com dois eixos de simetria, sendo dotadas de emendas com parafusos de alta resistência do tipo ASTM A325 de diâmetro 19 mm. Foram ensaiados oito vigas com comprimento de 3000 mm, sendo duas vigas de referência. Nas seis vigas restantes foram confeccionadas emendas em diferentes posições variando a quantidade de emendas. Todos os modelos estiveram solicitados por esforços de flexão simples até à ruptura, analisando os deslocamentos verticais, deslocamentos relativos à torção e as deformações específicas do aço. As ligações das vigas resistiram ao ensaio à flexão, não sendo constatada nenhuma ruptura nos parafusos e nem na chapa de ligação, apresentando cargas de ruptura entre 74% e 85% para as vigas da série com ligações. Consideravelmente as vigas com ligações não apresentaram cargas de ruptura muito inferiores às vigas de referência, com cargas de ruptura entre 78% e 100%. Os resultados indicam que as vigas com ligações parafusadas com parafusos de alta resistência são resistentes e por isso podem ser utilizadas por projetistas da área de estrutura metálica como mais uma opção.Submitted by Erika Demachki (erikademachki@gmail.com) on 2015-01-29T17:20:07Z No. of bitstreams: 2 license_rdf: 23148 bytes, checksum: 9da0b6dfac957114c6a7714714b86306 (MD5) Dissertação - Ronivon Soares Pereira - 2014.pdf: 2996792 bytes, checksum: f4e736b7c557dc7ccddb4806f63bfbaa (MD5)Approved for entry into archive by Erika Demachki (erikademachki@gmail.com) on 2015-01-29T17:43:00Z (GMT) No. of bitstreams: 2 license_rdf: 23148 bytes, checksum: 9da0b6dfac957114c6a7714714b86306 (MD5) Dissertação - Ronivon Soares Pereira - 2014.pdf: 2996792 bytes, checksum: f4e736b7c557dc7ccddb4806f63bfbaa (MD5)Made available in DSpace on 2015-01-29T17:43:00Z (GMT).
