Sensitivity of the numerical solution to finite element mesh for reinforced concrete deep beams
Abstract
An analysis of the influence of the manner of dividing the structure on the numerical solution of the static problems of the concrete and of the reinforced concrete deep beams, using a constitutive model of the concrete that demonstrates the material softening, is given. Detailed results of the numerical solutions are presented in the paper. The results indicate that taking into account the scale parameters makes it possible to increase the objectivity of the numerical results of modelling of the behaviour of concrete and reinforced concrete structures when the material softening is considered. The numerical analysis for the reinforced concrete deep beams indicates the differentiation of the obtained results according to the fracture energy values.
