This article proposes to use parabolic-linear diagram of deformation of steel fiber concrete under the conditions of compression. General principles of calculation method of steel fiber concrete elements. with the use of deformation diagrams of steel fiber concrete, have been submitted. The aim of this study was to present a method for calculating the deformation and deformation capacity steel fiber concrete bending elements based on the results of experimental studies. Results of tensile testing of samples allowed to put forward an analytical description of the time dependence of the stress-strain of steel fiber concrete in tension and compression, and accurately calculate the load and deflection bending elements. The experimental significance of the bearing capacity of steel fiber concrete bending elements on the fiber from the sheet and theoretical implications calculated by the proposed method have shown quite a good convergence.
