Results of nonlinear finite element analysis of several axially compressed, ring-stiffened, steel, cylindrical shells are presented, including comparisons with tests conducted at the Los Alamos National Laboratory. The specimens, all with radius-to-thickness ratio of about 450, have reinforced circular openings that cut across various numbers of ring stiffeners. The cylinders are loaded by enforced axial displacement applied to thick end plates halfway between the axis of revolution and the cylindrical shell wall. Measured imperfections are included in the analysis of a ring-stiffened specimen without any cutout. Inclusion of the imperfection field reduces the predicted collapse load by only eight per cent. Reinforced openings that cut one, two and three rings reduce the collapse load by 14, 21, and 22 per cent, respectively.
