Resumo: | This work presents the development of a parametric study on Crestbond shear connector through numerical modeling, evaluating its behavior with respect to strength and to the relative displacement between the concrete slab and the shear connector. The study covers the conception and improvement of numerical models for the parametric study, the development of an extensive research on the connector s parameters affecting its behavior, and an equation to predict the connector s ultimate strength, proposed at the end. The numerical models were created within the Finite Element software Abaqus, using nonlinear analysis and the concrete damaged plasticity model. The parametric study consisted on the analysis of 88 numerical simulations of push-out tests, as described on EN 1994-1-1:2004. The connection behavior was studied through these numerical tests. The obtained results allowed to define how each studied parameter influences the connector s behavior. It was also possible to define the desirable characteristics for the connector to be used in practice. In addition to these results, it was proposed a semi-empirical equation to evaluate the connector s ultimate strength which showed excellent correlation with most of the models, both experimental and numerical. |

O trabalho envolve o aperfeiçoamento e concepção de modelos numéricos para o estudo do conector, uma ampla investigação dos parâmetros que afetam o comportamento do conector, além da proposição de uma equação para a predição da sua capacidade resistente. Os modelos numéricos utilizados foram elaborados por meio do software de elementos finitos Abaqus, utilizando análise não-linear e o modelo de dano com plasticidade. O estudo paramétrico consistiu na análise de 88 simulações numéricas de ensaios tipo push-out, conforme a EN 1994-1-1:2004. Os resultados obtidos permitiram determinar como cada parâmetro estudado influencia o comportamento do conector e quais as características desejáveis para a aplicação do mesmo. Ao final do trabalho, propôs-se uma expressão semiempírica para a estimativa da carga máxima do conector que apresentou excelente correlação com grande parte dos modelos, tanto experimentais quanto numéricos.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de ViçosaMestrado em Engenharia CivilUFVBRGeotecnia; Saneamento ambientalEngenharia CivilConector de cisalhamentoCrestbondEstruturas mistasEstruturas metálicasMétodo dos elementos finitosCivil EngineeringShear connectorCrestbondComposite structuresMetal structuresFinite element methodCNPQ::ENGENHARIAS::ENGENHARIA CIVILEstudo do comportamento estrutural do conector Crestbond considerando variações geométricas e mecânicasStudy of the structural behavior of Crestbond connector considering geometrical and mechanical variationsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFVORIGINALtexto completo.pdfapplication/pdf3487297https://locus.ufv.br//bitstream/123456789/3838/1/texto%20completo.pdf440345c34c1ab5834f45b26ae9b87375MD51TEXTtexto completo.pdf.txttexto completo.pdf.txtExtracted texttext/plain276930https://locus.ufv.br//bitstream/123456789/3838/2/texto%20completo.pdf.txtb45ba984a25a28197372a3ecf76bcef8MD52THUMBNAILtexto completo.pdf.jpgtexto completo.pdf.jpgIM Thumbnailimage/jpeg3582https://locus.ufv.br//bitstream/123456789/3838/3/texto%20completo.pdf.jpgd465c9dbfca52b08e768d6fcb93b4205MD53123456789/38382016-04-09 23:18:42.128oai:locus.ufv.br:123456789/3838Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452016-04-10T02:18:42LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |
