Resumo:Perform serviceability verifications in reinforced concrete sections according to codes and standards needs the knowledge of strain and stress in steel bars within the section. For general axial and biaxial bending, obtaining the response equilibrium plane of the transversal section is a problem that has to be solved by means of a numerical method. This paper exposes a general approach for this purpose, based on moment curvature families of diagrams for the external axial load, and presents an experimental verification. The method is universal in terms of to external loads, shape of the transversal sections, and also constitutive models of materials involved.
