Abstract : A solution for the buckling loads of free rings is incorporated into an elementary analysis of ring-cylindrical shell interaction to obtain a method for computing external shell pressures which result in instability of stiffening rings. The method developed includes torsional as well as radial stability in the rings. Shell restraint of the rings is assumed only in the direction of the shell axis at the ring-shell intersection. It is shown that torsional and 'in-plane' buckling are independent for rings which have cross-sectional symmetry about their diametral plane. Two example problems are shown.
