Revista Eletrônica de Engenharia Civil, Goiânia, v. 12, n. 3, 2015/16. Disponível em: <https://www.revistas.ufg.br/reec/article/view/39300/pdf>.http://repositorio.bc.ufg.br/handle/ri/17359The analysis of structural elements, in a structure’s design, is an essential step to ensure good performance and stability of the structural system. In any types of structures, such as roofing in buildings, it’s usual using cold-formed steel beams due to their small weight. This research seeks to evaluate the structural efficiency of cold-formed steel beams when compared, for example, to compact welded steel beams. Thus, bending tests were performed in four simply supported beams submitted to two concentrated loads, in order to obtain pure flexure at the mid-span of the beams. These beams were instrumented for the determination of their rigidity and bending strength. The results showed that the cold-formed steel beam, box-shaped, presented structural efficiency similar to the welded steel beam “H” shaped.porAcesso AbertoVigas metálicasFlexãoPerfil formado a frioPerfis leves de açoEficiência estruturalSteel beamsFlexureCold-formedLightweight steel profilesStructural efficiencyArtigo10.5216/reec.v12i3.39300
