Creation of reinforced concrete constructions of ideally equal resistance is practically impossible, however maximum approximation to such solution should become the main purpose of constructions designing, since it provides for minimal materials consumption.Changing of total cross section of pre-stressed reinforcement along the span with the purpose of approximation to elements of equal resistance is possible during creation of stepped section of the element.In particular, the suggested solution allows to closely approximate the ideal beam of equal resistance, at which with decrease of external moment the height of element’s cross-section and the area of cross-section of extra-strong pre-stressed reinforcement are also decreased.In accordance with the existing reinforced concrete construction with the same class of concrete, reinforcement steel and load the suggested one due to more advanced profile is the most economic - the consumption of steel, concrete and weight of the beam are lower in it. This increases the ecological safety of constructions, as well
