Axial and circumferential critical buckling loads of thin cylindrical shell with stiffened rings are obtained by semi-analytical FEM. Then the interval widths of critical buckling loads which are obtained by interval analysis method are compared to those obtained by convex model method. The lower and upper bounds of axial and circumferential critical buckling loads increase with the increase of number of ring and are larger when the ring is placed on the inside of the shell than that is placed on the outside of the shell. The influence of variety of interval width of each basic variable on the variety of interval widths of critical buckling loads is obtained in this paper.
