Resumo: | This paper presents an experimental study done in bi-metal beams supported from 3000 mm in length, composed of thin-walled, resulting in a section of the "I". The beams were formed from the welding of the souls of two metal profiles of type U. The variables were the type of profile used, the quantity and positioning of the welded seams. The beams were divided into two groups where the first group used profiles of the "U" and the second group used simple profiles such as "U" stiff. Each group was composed of three beams so that a beam does not receive any amendment, another amendment received a girder high up in the middle of the span, and the third top beam was amended so that the position would result in an amendment pierced. The applied load was set so as to leave the central part of the beams, which served as a region of the present study, working in pure bending. Test results for beams without amendment were compared with the theoretical results and served as a parameter to compare the behavior of these beams, with beams that were amended. Also a comparison was made between the bearing capacity of the two groups of beams. The experiments showed that, by making the proper control of welding there is no problem in making welded seams in the rafters. We also observed that the simple addition of stiffening beams tables promotes a significant increase in the bearing capacity. There was no correlation between failure modes provided theoretically and observed experimentally, thus, further studies are needed to properly analyze the theoretical results with experimental results. |

As vigas foram formadas a partir da soldagem das almas de dois perfis metálicos do tipo U. As variáveis estudadas foram o tipo de perfil utilizado, a quantidade e o posicionamento das emendas soldadas. As vigas foram dividas em dois grupos onde, o primeiro grupo utilizou perfis do tipo U simples e o segundo grupo utilizou perfis do tipo U enrijecido. Cada grupo foi composto por três vigas de forma que uma viga não recebeu nenhum tipo de emenda, outra viga recebeu uma emenda de topo no meio do vão, e a terceira viga recebeu emendas de topo de forma que o posicionamento resultasse em uma emenda trespassada. O carregamento aplicado foi disposto de forma a deixar a parte central das vigas, que serviu como região de estudo deste trabalho, trabalhando em flexão pura. Os resultados dos ensaios para as vigas sem emenda foram comparados com os resultados teóricos e serviram de parâmetro para a comparação do comportamento destas vigas, com o das vigas que receberam emendas. Também foi feita uma comparação entre a capacidade portante dos dois grupos de vigas. Os experimentos constataram que, fazendo-se o controle adequado da soldagem não há problemas em se fazer emendas soldadas nas vigas. Também foi observado que o simples acréscimo de enrijecimento nas mesas das vigas promove um acréscimo significativo da capacidade portante. Não houve concordância entre os modos de ruptura previstos teoricamente e os observados experimentalmente, assim, são necessários mais estudos para se analisar adequadamente os resultados teóricos com os resultados experimentais.Made available in DSpace on 2014-07-29T15:03:30Z (GMT).
