In this work, by numerical simulation using the Abaqus software package, the stress–strain state of a bent reinforced concrete element of a rectangular cross section is investigated. Numerical modeling of the element is performed by volumetric finite elements, taking into account the non-linear (actual) state diagram of concrete, described by the model of plastic fracture of concrete with damage (CDP). Reinforcement is specified by rod finite elements, with a combination of elastic properties and metal plasticity model. The loading of the beam element in the model is performed statically with the application of concentrated forces at the centers of the thirds of the design span. As a result of the finite element calculation, the distribution of stresses in concrete and reinforcement according to Mises, deformations of finite elements along the main axes, as well as a model of concrete damage with increasing load were obtained. The results obtained showed a high convergence with the experimental data of testing beams for bending along a normal section, which allows using this algorithm for automated finite element analysis in the design of bending reinforced concrete structures.
