Resumo: This work presents a study of cold-formed steel (CFS) profiles not standardized by standard, lipped channel section with top flange inclined at 30°.  The goal is to determine an equation for the local buckling coefficient (kl) to apply the Effective Section Method (ESM) proposed by the Brazilian standard. Profiles are analyzed for axial compressive stress and simple bending moment. Analyzes were performed using GBTUL software. For the parametric study, 95 profiles with different geometric variations were developed. From the signature curves of each analysis, the respective critical axial compressive load values for local buckling and critical bending moment associated with local buckling are obtained. Using the Brazilian normative prescriptions and the results obtained, it was possible to determine the value of kl for each of the analyzed profiles. Thus, according to the Effective Section Method presented by the standard, two equations were proposed to determine the local buckling coefficient (kl), one for centered compression and one for bending moment around the axis of greatest inertia. The equations proved to be adequate to be used in the Effective Section Method for the type of profile presented, lipped channel section with flange inclined at 30°.

El objetivo de este trabajo es determinar una ecuación para el coeficiente de pandeo local (kl) para aplicar el Método de Sección Efectiva (MSE) propuesto por la norma brasileña. Los perfiles se analizan para determinar el esfuerzo de compresión axial y el esfuerzo de flexión simple. Los análisis se realizaron utilizando el software GBTUL. Para el estudio paramétrico se desarrollaron 95 perfiles con diferentes variaciones geométricas. A partir de las curvas de firma de cada análisis, se obtienen los respectivos valores de carga axial para pandeo local y momento flector asociado con pandeo local. Utilizando las prescripciones normativas brasileñas y los resultados obtenidos, fue posible determinar el valor de kl para cada uno de los perfiles analizados. Así, de acuerdo con el Método de Sección Efectiva presentado por la norma, se propusieron dos ecuaciones para determinar el coeficiente de pandeo local (kl), una para la compresión centrada y otra para la flexión simple alrededor del eje de mayor inercia. Las ecuaciones resultaron adecuadas para ser utilizadas en el Método de Sección Efectiva para el tipo de perfil presentado, U reforzado con una mesa superior inclinada a 30°.Este trabalho apresenta um estudo de perfis formados a frio não padronizados por norma, com tipologia U enrijecido (Ue) e mesa superior inclinada em 30°. O objetivo do trabalho é determinar uma equação para o coeficiente de flambagem local (kl) para aplicação do Método da Seção Efetiva (MSE) proposto pela norma brasileira. Os perfis são analisados para o esforço axial de compressão e para esforço de flexão simples. As análises foram realizadas no software GBTUL. Para o estudo paramétrico, foram desenvolvidos 95 perfis com diferentes variações geométricas. A partir das curvas de assinatura de cada análise obtém-se os respectivos valores de carga axial referente a flambagem local e momento fletor associado à flambagem local. Com uso das prescrições normativas brasileiras e dos resultados obtidos, foi possível determinar o valor de kl para cada um dos perfis analisados. Assim, de acordo com o Método da Seção Efetiva apresentado pela norma, foram propostas duas equações para a determinação coeficiente de flambagem local (kl), uma para a compressão centrada e outra para a flexão simples em torno do eixo de maior inércia. As equações mostraram-se adequadas para serem utilizadas no Método da Seção Efetiva para a tipologia de perfil apresentada, U enrijecido com mesa superior inclinada em 30°.Research, Society and Development2021-09-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2025410.33448/rsd-v10i12.20254Research, Society and Development; Vol. 10 No. 12; e92101220254Research, Society and Development; Vol. 10 Núm. 12; e92101220254Research, Society and Development; v. 10 n. 12; e921012202542525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/20254/18005Copyright (c) 2021 Lucas Roquete; Matheus Miranda de Oliveira; Fábio Nogueira da Silva Costa; Larissa Vieira Marinho; Arlene Maria Cunha Sarmanhohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRoquete, LucasOliveira, Matheus Miranda deCosta, Fábio Nogueira da SilvaMarinho, Larissa VieiraSarmanho, Arlene Maria Cunha2021-11-14T20:26:51Zoai:ojs.pkp.sfu.ca:article/20254Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:39:57.477062Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
