Experimental investigation of the buckling of nuclear containment-like cylindrical geometries under combined shear and bending

This paper describes the method for and results of, determining the static buckling interaction curves for both ring-stiffened and unstiffened cylindrical geometries that have radius-to-thickness (R/t) ratios and other parameters characteristic of nuclear steel containments. The purpose of developing these test methods and interaction curves is to have this information available for a dynamic buckling study on the same or similar shells that will be directed at answering questions regarding the freezing-in-time analysis method.
