The article considers a calculation method of compress reinforced concrete elements of various flexibility. The calculation method is based on theoretical principles of solid mechanics and on the basic laws of force resistance of compressed reinforced concrete elements. It presents the disadvantages of limited practical application of this calculation method within current design standard. The study describes a new method on the pattern of fasten hinged rod. This rod has a constant cross-section along the length of the element loaded with an eccentrically applied compressive force. The calculation of bending moments and various stiffnesses the compressed rod of normal sections along the length of impact on the curvature rod. This allows an accurate determination of flexible elements deflection, and their bearing capacity. The calculations results clearly show the process of bearing capacity of rod of strength of the normal section loss, and the process loss of stability of the second kind. Comparison of the calculation results with the published experimental data have confirmed better reliability of deformation calculation according to the current design standard.
