Resumo: The main attractive features of composite structures are the ability to explore the best characteristics of the steel and concrete material. These structures have an excellent structural performance, geometric precision and very low waste in civil construction work. In addition, the use of steel-concrete composite beams with hollow core slabs favors the industrialization process of the civil construction sector, in addition to allowing greater agility in the execution and drastic reduction in the amount of debris generated on site. When steel-concrete composite beams are requested at a negative hogging moment, in continuity regions, the concrete slab lies in traction and the steel profile in compression, which is not ideal in the use of steel-concrete composite beams. Thus, the steel profile is subject to stability phenomena. Among the stability modes that are verified in the steel profile there are the lateral distortional buckling (LDB), the flange local buckling (FLB) and the web local buckling (WLB). In the case of LDB, the standard procedures and the literature review show that this phenomenon is not yet fully understood. Furthermore, no investigation has been carried out considering the use of hollow core slabs. In this context, in order to investigate this phenomenon, this work presents a numerical study, developed with the ABAQUS software, in composite beams with hollow core slabs under the action of negative hogging moment. The results were compared with analytical procedures. It was found a conservative situation for all the procedures studied.

Essas estruturas apresentam um excelente desempenho estrutural, precisão geométrica e baixíssimo desperdício em obra. Além disso, a utilização de vigas mistas de aço e concreto com lajes alveolares pré-fabricadas favorece o processo de industrialização do setor da construção civil, além de possibilitar maior agilidade na execução e diminuição drástica da quantidade de entulho gerado em obra. Quando as vigas mistas de aço e concreto são solicitadas a momento fletor negativo, em regiões de continuidade, a laje de concreto se encontra tracionada e o perfil de aço comprimido, situação não ideal na utilização de vigas mistas de aço e concreto. Assim, o perfil de aço está sujeito a fenômenos de estabilidade. Dentre os modos de estabilidade que são verificados no perfil de aço tem-se a Flambagem Lateral com Distorção (FLD), a Flambagem Local da Mesa (FLM) e a Flambagem Local da Alma (FLA). Se tratando da FLD, os procedimentos normativos e os trabalhos presentes na literatura mostram que esse fenômeno ainda não se encontra totalmente esclarecido. Além disso, nenhuma investigação foi desenvolvida considerando-se a utilização de lajes alveolares pré-fabricadas. Nesse contexto, com o objetivo de investigar esse fenômeno, esse trabalho apresenta um estudo numérico, desenvolvido com o software ABAQUS, em vigas mistas com lajes alveolares sob ação de momento fletor negativo. Os resultados foram comparados com procedimentos analítico. Verificou-se situação conservadora para todos os procedimentos estudados.Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte2022-12-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www2.ifrn.edu.br/ojs/index.php/HOLOS/article/view/10284HOLOS; v. 8 (2022)1807-1600reponame:Holosinstname:Instituto Federal do Rio Grande do Norte (IFRN)instacron:IFRNporhttp://www2.ifrn.edu.br/ojs/index.php/HOLOS/article/view/10284/3679Copyright (c) 2022 HOLOShttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessRossi, AlexandreNicoletti, Renato Silvade Souza, Alex Sander ClementeMartins, Carlos Humberto2023-04-13T04:43:42Zoai:holos.ifrn.edu.br:article/10284Revistahttp://www2.ifrn.edu.br/ojs/index.php/HOLOSPUBhttp://www2.ifrn.edu.br/ojs/index.php/HOLOS/oaiholos@ifrn.edu.br||jyp.leite@ifrn.edu.br||propi@ifrn.edu.br1807-16001518-1634opendoar:2023-04-13T04:43:42Holos - Instituto Federal do Rio Grande do Norte (IFRN)false
