Numerical simulation of the mechanical performance of deep beam

Resumo

The purpose of this paper is the analysis of the mechanical performance of concrete deep beams. To overcome the shortcomings inherent to the traditional models, the finite element method on a non linear orthotropic model is employed. The obtained results showed that the practiced range on reinforcement did not influence, significantly, the beam performance, one testifies a behavior, in the overall way, pursuant the fashion accepted in the scientific literature on the subject. Nevertheless, it should be detached that the structural element failure resulted from the concrete crushing on the region beneath the load, in addition to the occurrence of horizontal tensile stress and “snap back”, at the upper edge in the center region, for the beams of greatest height.
