Abstract: In this paper, the problem of bending of a multilayered rod by transverse loads in the presence of zones of elastic and nonlinear-inelastic deformation is considered, the retios are obtained to determine the boundary between the elastic and nonlinear-inelastic areas of deformation of the rod. Various cases of the position of the specified boundary between areas are considered, depending on external loads. The expressions for ultimate loads are given for each of the characteristic cases of the location of these boundaries: the first (deformation reaches the limit elastic value) and the second (deformation reaches the value of pre-fracture deformation).

Keywords: concrete rods, analytical solutions, physical nonlinearity, elasticity, transverse loads.
