In response to this challenge, a comparative study was conducted to explore various approaches for calculating the critical moment. This involved both analytical and numerical analyses, using different methods available in codes and computational tools. The analytical analysis followed the Effective Width Method, employing the expression proposed in ENV 1993-1-1:1992, which is commonly used for evaluating the critical lateral\u2013torsional moment of hot-rolled profiles. Numerical analyses were then performed using the ABAQUS v6.13, GBTUL v2.0, and CUFSM v5.05 software packages. The ABAQUS model, validated with results obtained from an experimental campaign, serves as the reference model. Upon assessing the bending moment resistances according to European, Brazilian, and American standards, consistency was found among these standards. However, it became evident that using the analytical expression proposed for hot-rolled profiles is inadequate for evaluating the critical lateral\u2013torsional moment of CFS omega-shaped profiles. Conversely, the agreement between the ABAQUS, GBTUL, and CUFSM results suggests their utility as reliable tools for estimating the elastic critical lateral\u2013torsional buckling moment.<\/jats:p>","DOI":"10.3390\/app14093857","type":"journal-article","created":{"date-parts":[[2024,4,30]],"date-time":"2024-04-30T09:50:07Z","timestamp":1714470607000},"page":"3857","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Global Buckling Resistance of Cold-Formed Steel Beams with Omega-Shaped Sections"],"prefix":"10.3390","volume":"14","author":[{"given":"Rita","family":"Peres","sequence":"first","affiliation":[{"name":"CONSTRUCT, Faculdade de Engenharia da Universidade do Porto, 4200-465 Porto, Portugal"}]},{"given":"Jos\u00e9","family":"Carvalho","sequence":"additional","affiliation":[{"name":"CONSTRUCT, Faculdade de Engenharia da Universidade do Porto, 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-7097-4874","authenticated-orcid":false,"given":"Jean Antonio","family":"Emerick","sequence":"additional","affiliation":[{"name":"Departamento de Engenharia Civil, Universidade Federal de Vi\u00e7osa, Vi\u00e7osa 36570-900, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4844-7560","authenticated-orcid":false,"given":"Lu\u00eds","family":"Macedo","sequence":"additional","affiliation":[{"name":"Departamento de Engenharia Mec\u00e2nica, Instituto Superior de Engenharia do Porto, 4249-015 Porto, Portugal"}]},{"given":"Jos\u00e9 Luiz","family":"Rangel Paes","sequence":"additional","affiliation":[{"name":"CONSTRUCT, Faculdade de Engenharia da Universidade do Porto, 4200-465 Porto, Portugal"},{"name":"Departamento de Engenharia Civil, Universidade Federal de Vi\u00e7osa, Vi\u00e7osa 36570-900, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9732-9969","authenticated-orcid":false,"given":"Jos\u00e9 Miguel","family":"Castro","sequence":"additional","affiliation":[{"name":"CONSTRUCT, Faculdade de Engenharia da Universidade do Porto, 4200-465 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"34","DOI":"10.1002\/cepa.1262","article-title":"Mode Interaction in Cold-Formed Steel Members: State-of-Art Report","volume":"4","author":"Camotim","year":"2021","journal-title":"ce\/papers"},{"key":"ref_2","unstructured":"(2006).
