Buckling investigation of ring-stiffened cylindrical shells with reinforced openings under unsymmetrical axial loads
Four steel shells having features representative of steel containment vessels for nuclear power plants were fabricated and tested to failure under unsymmetrical axial loading. All of the ring-stiffened shells were 698 mm (27.5 in.) in diam by 0.762 mm (0.030 in.) in wall thickness. Each one had a penetration that was reinforced in accordance with the area-replacement rule of the applicable American Society of Mechanical Engineers (ASME) code and of a design to simulate actual practice for steel containments. The penetrations were of four different diameters, cutting no ring stiffeners, and cutting one-, two-, and three-ring stiffeners. Before testing, imperfections were measured, and strain gages were applied to characterize the strain field at an end and around the penetration. Buckling loads were determined.
