Uma abordagem experimental e numérica para determinação de curvas de compressão para concreto simples e reforçados com fibras de aço

Abstract: RESUMO A curva tensão-deformação do concreto é importante para o dimensionamento de estruturas, pois por meio dela é possível obter sua resistência à compressão, sua deformação de pico, o módulo de elasticidade e a tenacidade do concreto. Entretanto, essa é uma propriedade que não é comumente determinada nos ensaios de controle de qualidade do concreto, sendo normalmente controlada apenas a resistência à compressão. Contudo, quando se utiliza de métodos mais refinados para projeto de estruturas de concreto, co… Show more

“…In the inverse analysis problem, the results provided in a given experiment, for example, are used to determine the input data of the direct problem, or the input data are used to determine the properties of a system [1][2][3]. Reference [4] uses direct analysis (a procedure that requires the definition of the form of the constitutive relationship, in order to simulate the uniaxial behavior of the material) and inverse analysis, which deals with the interactive solution to determine stress-strain or stress-opening diagrams of cracks based on the adjustment of experimental results through constitutive relations.…”
