Abstract: This paper considers the problem of bending a multilayer rod under transverse loads in the presence of zones of elastic and nonlinear-inelastic deformation, and relations are obtained to determine the interface between the elastic and nonlinear-inelastic deformation regions of the rod. Numerical calculations were obtained for the cases of coincidence and non-coincidence of the neutral line with the axis of the rod. Numerical calculations of the ultimate loads are presented: the first (the deformation reaches the limiting inelastic value) and the second (the deformation reaches the value of the pre-fracture strain).

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