description: This work is devoted to determining the area of rational use of high-strength concrete in bending elements, as well as developing recommendations for the design of these elements of the load-bearing frame using high-strength concrete. The research set the following goals: 1. Study of the effectiveness of the use of high-strength concrete in bending elements without prestressing the reinforcement. 2. Study of the effectiveness of the use of high-strength concrete in bending elements with prestressed reinforcement. 3. Analysis of the results and development of design recommendations based on the data obtained. A theoretical study was carried out to identify areas of effective use of high-strength concrete in bending elements by performing calculations for I and II groups of limit states according to regulatory documents of the Russian Federation, taking into account the estimated cost of materials in St. Petersburg. The calculation results are displayed in graphs of dependencies of various values, which allows us to visually assess the areas of effective use of high-strength concrete in the considered reinforced concrete structures. Recommendations on the use of high-strength concrete in bending reinforced concrete elements without prestressing and with prestressed reinforcement have been compiled. For the rational use of materials in the design of rectangular beams, it is advisable to use the recommendations given in the work, and then perform a clarifying calculation based on the initial data set in the problem being solved. To achieve these results, the following information technologies were used in the work, including software, cloud services, databases, and others: Mendeley, digital library "eLIBRARY.RU ", SCAD Office, Maple.
