Resumo: | Carbon steel rolled angles have often been used as a structural element without the alternative of another type of steel. This work aims to propose the study of the structural behaviour of a new type of steel, the stainless steel, which will be evaluated when subjected to axially centred compression. The structural element will be composed of a column of laminated profile L also known as angle bracket. Current stainless steel design standards are largely based on assumed analogies with the behaviour of carbon steel structures. For the understanding of the structural behaviour of the stainless steel, it was initially carried out experimental tests in carbon steel for three types of cross section 64x64x4,8, 76x76x6,4 and 102x102x6,4 with variable length from 272mm to 1517mm, the results were compared with the recommended calculation method in Eurocode 3, Part 1-1. This process was important to calibrate and validate the proposed experimental model. With the experimental process defined, the tests were started with stainless steel rolled angles with the same cross-sections of the carbon steel tests, however the length varied from 152mm to 1893mm. Finally, these results were compared with the calculation method proposed in Eurocode 3, Part 1-4. The ruin mode presented for laminated angles of less than or equal to 500mm in carbon steel and stainless steel was the local buckling of the corner flanges, for the 64x64x4.8 and 76x76x6.4 carbon steel angles the flexural-torsional buckling occurred in lengths equal to 750mm and with 945mm for the angle 102x102x6,4. In the other angles in carbon steel with length in the range of 1000mm to 1500mm the failure mode was flexural buckling. For the angles in stainless steel the failure mode was flexural-torsional buckling in the lengths between 500mm to 1480mm and between 147mm to 1893mm, flexural buckling. It has been found that the calculation criteria advocated by Eurocode 3, Part 1-1 and Eurocode 3, Part 1-4 are conservative and that the values of and λ_0 proposed by Eurocode 3, Part 1-4 are not valid for steel rolled angles stainless. |

Este trabalho tem como objetivo apresentar um estudo do comportamento estrutural de elementos em aço inoxidável submetidos a compressão axial centrada por meio de ensaios de análise experimental. As atuais normas de projeto de aço inoxidável são em grande parte, baseadas em analogias assumidas com o comportamento de estruturas de aço carbono. Para um melhor entendimento do comportamento estrutural do aço inoxidável foram realizados, inicialmente, ensaios experimentais em cantoneiras de aço carbono de três diferentes seções transversais com comprimento variável de 272mm a 1517mm. Os resultados foram comparados com o método de cálculo preconizado no Eurocode 3, Parte 1-1. Os ensaios possibilitaram a calibração e validação o modelo experimental proposto. Com o processo experimental definido foram iniciados os ensaios com as cantoneiras laminadas em aço inoxidável com as mesmas seções transversais dos ensaios em aço carbono, porém o comprimento teve variação de 152mm a 1893mm. Por fim, estes resultados foram comparados com método de cálculo proposto no Eurocode 3, Parte 1-4. O modo de ruína apresentado para cantoneiras laminadas com comprimentos até 500mm, tanto em aço carbono quanto em aço inoxidável, foi a flambagem local das abas das cantoneiras; para as cantoneiras em aço carbono 64x64x4,8 e 76x76x6,4, a flambagem por flexo-torção ocorreu em comprimentos iguais a 750mm e 945mm, respectivamente e para a cantoneira 102x102x6,4 com comprimentos de 407 a 1480mm. Nas demais cantoneiras em aço carbono com comprimento dentro do intervalo de 1000mm a 1500mm, o modo de ruína foi a flambagem por flexão. Nas cantoneiras em aço inoxidável, o modo de ruína foi a flambagem por flexo-torção nos comprimentos entre 500mm e 1480mm e flambagem por flexão entre 1470mm e 1893mm. Verificou-se que os critérios de cálculo preconizados pelo Eurocode 3, Parte 1-1 e Eurocode 3, Parte 1-4 são conservadores e que os valores de e λ_0 propostos pelo Eurocode 3, Parte 1-4 não são válidos para as cantoneiras laminadas em aço inoxidável.Submitted by Boris Flegr (boris@uerj.br) on 2021-01-06T14:45:11Z No. of bitstreams: 2 Alan da Silva Sirqueira_PT.pdf: 785216 bytes, checksum: a05f367c8fa0e1c7052bf3328619c250 (MD5) Alan da Silva Sirqueira_T.pdf: 15292037 bytes, checksum: c6d7577af205a320f1a5e4e90638e118 (MD5)Made available in DSpace on 2021-01-06T14:45:11Z (GMT).
