    Abstract. The method of direct determination of the transverse force in inclined sections of reinforced concrete structures is described. At the same time, the emphasis is on the practical side of the method. The main problems of determining the transverse force in inclined sections are associated with finding chipping stresses in concrete and with the shape of the normal stress diagram in the design section in the absence of principles of practical separation of the forms of destruction of inclined sections from concrete compression or its section. In this paper, based on the accepted form of the compression stress diagram with a cutout in a normal section passing through the tip of an inclined crack, a criterion for separating the forms of destruction from compression or cut concrete is given. The height of the compressed zone in this section is determined from the joint solution of the moment equilibrium equations for normal and inclined sections based on tests of experimental aerated concrete and heavy concrete beams. For practical calculations, the formula of the transverse force in inclined sections is derived. This work is devoted to the search for approaches to the practical solution of these problems.
    Key words: direct calculation of transverse force, reinforced concrete structures, aerated concrete and heavy concrete beams, inclined section, tangential stresses, diagram of compression stresses.
