Abstract

Under stresses close to the ultimate stresses, a reinforced concrete section yields and cracks. The calculation in linear elasticity no longer makes it possible to evaluate the real deformations of the section. One is then led to make a study in nonlinear elasticity. The object of this work is the elaboration of a calculation method in nonlinear elasticity, allowing the simulation until the failure of reinforced concrete sections subjected to a compound deviated bending taking into account the real behavior laws (nonlinear) of the materials (steel and concrete). A computer program is developed following FORTRAN standards, and then confronted with the obtained experimental results on failure tests of sections subjected to deflected bending. The comparison between the numerical simulation and the experimental test/calculation shows the achievement of satisfactory results.
