Resumo: | This work presents a discussion on the employment of a damage model recently proposed for concrete and other damage models in the non-linear analysis of reinforced concrete structures. The validation of the model is obtained by the comparison between numerical responses and experimental ones. The model proposed by Pituba regards concrete as an initially isotropic medium that starts to present plastic deformations, bimodularity and anisotropy induced by the damage. The model proposed by Mazars considers concrete to be an elastic and isotropic medium. Next, the model proposed by La Borderie is presented. This isotropic damage model takes into account plastic deformations induced by the damage. In the second part of the work, the models are used in the analysis of reinforced concrete structures, where the numerical responses are compared with experimental ones. The results evidence the good performance of the damage models on the simulation of the behavior of reinforced concrete structures. In particular, the employment of the damage model proposed by Pituba is valid. It is noted that the simple formulations of damage models can present results with good accuracy leading to possible practical applications in Structural Engineering. |

O modelo proposto admite o concreto como meio inicialmente isótropo e que passa a apresentar deformações plásticas, bimodularidade e anisotropia induzidas pelo dano. Já o modelo proposto por Mazars considera o concreto como meio elástico e isótropo. Em seguida, apresenta-se a formulação do modelo proposto por La Borderie, que leva em conta deformações plásticas induzidas pelo dano e mantém a característica de isotropia do material. Na segunda parte do trabalho, os modelos são empregados na análise de vigas e pórtico em concreto armado, e as respostas numéricas são confrontadas com medidas experimentais. Os resultados evidenciam o bom desempenho dos modelos de dano e, em particular, valida-se o emprego do modelo proposto por Pituba nas situações estudadas. Observa-se ainda que formulações simples de modelos de dano para o concreto podem apresentar resultados bastante satisfatórios, dando margem para possíveis aplicações na prática da Engenharia de Estruturas.Universidade Estadual De Maringá2010-11-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/700910.4025/actascitechnol.v32i3.7009Acta Scientiarum.
