Resumo: | Cold-formed steel profiles are a light and economic structural solution. They usually have high slenderness and are under buckling modes that can reduce their resistance. They often have perforations to fit connections or installations, that may potentialize the resistance reduction. As a solution, stiffeners in holes borders can be used. This work analyzes stiffened perforations effects in channel columns under local and distortional buckling by Finite Element analysis. It was observed that stiffened perforations increased the columns under local buckling resistance, and the perforations diameter and stiffener length have remarkable influence in analyzed columns. |

Numerical Analysis of Cold-formed Channel Sections with Stiffened Holes Under Axial CompressionAnálise Numérica de Perfis Formados a Frio do tipo U Enrijecido com Perfurações Enrijecidas Submetidos à CompressãoCold-formed steel profiles are a light and economic structural solution.

No entanto, sua esbeltez induz modos de flambagem que podem reduzir sua resistência, fato agravado pela frequente existência de perfurações para fins de ligações ou compatibilização com instalações elétricas ou hidrossanitárias. Como possível solução, existe o emprego de enrijecedores nas bordas das perfurações. Este trabalho avaliou o efeito de perfurações enrijecidas em pilares sujeitos aos modos local e distorcional por meio de análise pelo método dos elementos finitos. Foi observado o efeito positivo das perfurações enrijecidas no aumento da resistência de pilares sujeitos ao modo local, e fatores como o diâmetro da perfuração e o comprimento do enrijecedor são importantes para o bom funcionamento desta solução.Escola Politécnica de Pernambuco2023-05-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttp://revistas.poli.br/index.php/repa/article/view/219310.25286/repa.v8i2.2193Journal of Engineering and Applied Research; Vol 8 No 2 (2023): Revista de Engenharia e Pesquisa Aplicada; 1-10Revista de Engenharia e Pesquisa Aplicada; v. 8 n. 2 (2023): Revista de Engenharia e Pesquisa Aplicada; 1-102525-425110.25286/repa.v8i2reponame:Revista de Engenharia e Pesquisa Aplicadainstname:Universidade Federal de Pernambuco (UFPE)instacron:UFPEporhttp://revistas.poli.br/index.php/repa/article/view/2193/871http://revistas.poli.br/index.php/repa/article/view/2193/872de Nicolau, Igor Amaral NevesSarmanho, Arlene Maria Cunhade Souza, Flávio Teixeirainfo:eu-repo/semantics/openAccess2023-06-12T13:25:36Zoai:ojs.poli.br:article/2193Revistahttp://revistas.poli.br/index.php/repaONGhttp://revistas.poli.br/index.php/repa/oai||repa@poli.br2525-42512525-4251opendoar:2023-06-12T13:25:36Revista de Engenharia e Pesquisa Aplicada - Universidade Federal de Pernambuco (UFPE)false |
