The article presents the solution of the problems of stability in the bending-torsion shape of the core elements of continuous-step arches beyond the elastic limit. This solution is based on deformation theory of plane elastic archy rods (“Rod” algorithm) and “Cross-Section” algorithm, which allows taking into account the development of plastic deformations. Graphs of the dependence of stability coefficients on curvature, reduced flexibility and relative eccentricities are given.
