The paper presents theoretical prerequisites for calculation of steel-fiber-reinforced concrete members subjected to bending according to the nonlinear deformation model. The charts of deformation used in calculation were received at test of the steel-fiber-reinforced concrete prismatic samples for central compression and tension. Conclusions of working formulas on the definition of deformation modules and the corresponding tensions depending on test charts of steel-fiber-reinforced concrete deformation are made. The calculation of well-known formulas is submitted, the formulas, besides charts of the material`s condition, being the basis of the proposed calculation procedure.
