Title: Buckling investigation of ring-stiffened cylindrical shells with reinforced openings under unsymmetrical axial loads

Technical Report ·
OSTI ID:6488862

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.
