AN ULTIMATE STRENGTH ANALYSIS TECHNIQUE FOR CROSS-STIFFENED BULKHEADS UNDER COMBINED INPLANE BENDING AND SHEAR

An analytical method is presented for evaluating the ultimate strength of cross-stiffened bulkheads under combined inplane bending and shear associated with collapse in the panel mode, the case of a general collapse not being considered. The method and the related computer program should be useful to the designer for evaluating the margin of safety against bulkhead collapse under high-shear-low moment conditions. The analysis includes a calculation of the buckling and tension field, postbuckling, strength contributions of the unstiffened plate components in a bulkhead panel and a discussion of the effect on panel strength of premature stiffener buckling.
