The deformation model is a fairly flexible tool, which allows solving a wide range of problems in the design of reinforced concrete structures. At the same time, important tasks are the choice of a material stress-strain diagram that most accurately reflects the deformation of the structure under the accepted conditions, and the assessment of the influence of the type of the accepted diagram on the results of calculating the bearing capacity and deformations of the structure. The article compares the results of calculating the bearing capacity and curvature of beams depending on the shape of the accepted concrete deformation diagram and the structural parameters of the element (section height and reinforcement ratio).

Keywords: deformation model, stress-strain diagram, bending element, transverse section
