Development of a software for the numerical modeling of reinforced concrete sections - AlfaMCV

Abstract In the design of reinforced concrete structures, the usual procedure is the inclusion of safety factors, according to the Brazilian Standards, to allow the structure to withstand loads above the ones predicted and a possible collapse. Since concrete has greater resistance to compression than tension, the design of this type of structures disregards its contribution in terms of tensile forces. In this way, the present work aims to analyze the contribution of the tension region of the concrete when submitted to a bending moment. Finally, based on this mathematical model, a software is developed to represent the behavior of a beam (strains, curvature and deflections), according to the application of a resisting bending moment, up to rupture.
