“…Eventually, such method should be sufficiently reliable, relatively simple and flexible to calculate a wide range of varying possibilities for the conditions of fastening, loading, structural forms of sections and reinforcement parameters. For structures operating under transverse bending conditions, the corresponding solutions were obtained in the works [1,3,4,6,7]. For conditions of longitudinal-transverse bending, there are no corresponding solutions.…”

“…The loss of operational qualities of reinforced concrete structures, as noted in many experimental studies [1,[4][5][6][7][8][9][10][11] is characterized by limit deformations *i   (under compression) and *i   (under tension). Their excess usually leads to intense fracture processes [11,12].…”

“…The further solution of the problem is reduced to the numerical solution of a system of two nonlinear algebraic equations with respect to two unknowns and the subsequent calculation of the deformation by formulas ( 6)- (7). Moreover, the deformation for each layer must be in the interval *…”

The longitudinal transverse bending of multilayer rods made of reinforced concrete of arbitrary cross-section is considered. It is assumed that the coefficients in the connection equation between stresses, strains and temperature are different in each layer. The achievement of maximum deformation of the permissible limit value at stretching or compression is accepted as the criterion of conditional limit state in the i-layer. The case of longitudinal-transverse bending of a hinged rod is considered as an example of this method of solution. The distribution of bending moments and longitudinal forces, displacements and deformations is determined.

“…Such method should be sufficiently reliable, relatively simple and flexible to take into account a wide range of possible variations of conditions of fastening, loading and structural forms of sections. The corresponding solutions for structures operating under flat bend conditions are obtained in the works [1], [2], [3], [4]. For complex bend conditions, the corresponding solutions are absent.…”

The problem of complex bend of multilayered rods based on concrete is considered. It is assumed that the rod of constant cross-section is of arbitrary shape and diﬀerent brands of concrete are used in the cross-section of the rod layer by layer. The solution is sought by the small parameter method. The case of a complex bend of the rod pinched at both ends is considered as an example of this solution method. The distribution of bending moments and longitudinal forces in the zero and first approximations is determined.
