Resumo: | Technological advancement has led to the development of computer programs with great capacityto represent the reality of reinforced concrete structures. Each software has particularities resultingfrom the different mathematical methods used in its algorithm, so that they present different results regarding the stresses, deformations and displacements of the structures. This paper evaluatedstructural aspects of the slabs of the standard floor of a collective housing composed of fifteenstandard floors, considering two different numerical analyzes (grid and finite element method, MEF),using the software SAP2000 V14® and Eberick V8®, respectively. The maximum positive andnegative moments, maximum displacements, processing time and number of nodes generated wereevaluated in order to subsequently make the quantitative and qualitative comparison between themethods, as well as the budgets from each dimensioning. Regarding the results obtained, the gainand computational time between the methods used were not very significant, however, the MEFprovided smaller quantities, with a significant reduction in steel for the slabs. Thus, althoughstructural safety has been evaluated and achieved for both methods used, the article shows that theFEM is preferable to the grid method, considering mainly the cost reduction provided for the projectused in the case study. |

Cada software apresentaparticularidades decorrentes dos diferentes métodos matemáticos empregados em seus algoritmos,de modo que apresentam resultados distintos quanto as tensões, deformações e deslocamentos dasestruturas. Este artigo avaliou aspectos estruturais das lajes do pavimento tipo de uma habitaçãocoletiva composta por quinze pavimentos tipo, considerando duas análises numéricas distintas(método das grelhas e dos elementos finitos, MEF), utilizando os softwares SAP2000 V14® e EberickV8®, respectivamente. Foram avaliados os momentos positivos e negativos máximos, flechasmáximas, tempo de processamento e número de nós gerados para posteriormente, efetuar acomparação quantitativa e qualitativa entre os métodos, bem como os orçamentos provenientes decada dimensionamento. Com relação aos resultados obtidos, o ganho e o tempo computacional entreos métodos utilizados foram pouco expressivos, porém, o MEF proporcionou menores quantitativos,com significativa redução de aço para as lajes. Dessa forma, apesar da segurança estrutural ter sidoavaliada e alcançada para ambos os métodos utilizados, o artigo evidencia que o MEF é preferível aométodo das grelhas, considerando principalmente a redução de gastos proporcionada para o projetoutilizado no estudo de caso.Escola Politécnica de Pernambuco2020-12-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttp://revistas.poli.br/index.php/repa/article/view/143110.25286/repa.v6i1.1431Journal of Engineering and Applied Research; Vol 6 No 1 (2021): Revista de Engenharia e Pesquisa Aplicada; 73-83Revista de Engenharia e Pesquisa Aplicada; v. 6 n. 1 (2021): Revista de Engenharia e Pesquisa Aplicada; 73-832525-425110.25286/repa.v6i1reponame:Revista de Engenharia e Pesquisa Aplicadainstname:Universidade Federal de Pernambuco (UFPE)instacron:UFPEporhttp://revistas.poli.br/index.php/repa/article/view/1431/705http://revistas.poli.br/index.php/repa/article/view/1431/706-Copyright (c) 2020 Guilherme Coelho Fava, -, Sávio Aparecido dos Santos Pereira, Thiago Augusto Mendes, -, Murilo Meiron Pádua Soares, -http://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessFava, Guilherme Coelhodos Santos Pereira, Sávio AparecidoMendes, Thiago AugustoPádua Soares, Murilo Meiron2021-07-13T08:40:37Zoai:ojs.poli.br:article/1431Revistahttp://revistas.poli.br/index.php/repaONGhttp://revistas.poli.br/index.php/repa/oai||repa@poli.br2525-42512525-4251opendoar:2021-07-13T08:40:37Revista de Engenharia e Pesquisa Aplicada - Universidade Federal de Pernambuco (UFPE)false |
