| Resumo: | The numerical simulation results of the fracture process in re-inforced concrete shear panels are presented in this work. The simulation used a model based on the continuum strong dis-continuity approach (CSDA) and mixing theory. CSDA des-cribes strain localization and formation of discontinuity asso-ciated with the appearance of a crack. On the other hand, mixing theory represents composite material behaviour which is formed by a simple concrete matrix and one or two bundles of long reinforcement bars. The behaviour of simple concrete and steel is represented by a two-dimensional damage model and one-dimensional plasticity model, respectively. The mo-del has been implemented in the finite element method which considers plane stress, infinitesimal strain and static loads. Three panels are simulated, reinforced in one or two ways; they are mainly subjected to shear forces. The numerical si-mulation results as well as structural response and cracking patterns were satisfactory. |
