Application boundaries of the truss analogy and disk model methods to the strength calculation of reinforced concrete flexuralelements inclined sections are established. Areas of structures failure by virtual compressed element (inclined strip) andcompressed zone over dangerous inclined crack under the shear force are determined. The criterion of minimum limit force,which is perceived by the elements, is applied. Influence of concrete class, relative shear span and transverse reinforcementintensity on elements strength based on variational method in plasticity theory is specified. The data concerning the values ofthe transverse reinforcement coefficient at the boundaries of the failure from shear within the inclined strip and compressedzone over the dangerous crack are obtained.
