Annotation: The results of the calculation of reinforced concrete beams with a limited displacement of the support sections in the horizontal direction are presented. The calculations were performed using the Lyra-SAPR software package, taking into account the physical non-linearity of materials deformation. Two computational models of a single-span beam are considered: in the form of a flat scheme of beam-wall plates and in the form of a volume scheme of bulk finite elements. The diagrams of deformation of concrete and reinforcement used in the performance of nonlinear calculations are given. Produced a quantitative assessment of the accuracy of the calculation results compared with the test results experienced beams. Recommendations on the choice of the design model for the specific purposes of the calculations are given.
Keywords: beams, reinforced concrete, thrust, diagrams, design model, bearing capacity.
