Description: A generalized crippling analysis for short monolithic panels with formed or extruded stiffeners is presented. The analysis applies to monolithic panels. Criteria are given for rivete panels which indicate if the panels can be considered to behave in a monolithic manner. Riveted panels that are subject to interrivet buckling and wrinkling or forced crippling do not behave in this manner. Methods are presented for estimating the strength of such panels.

Intermediate-length and long stiffened panels are subject to other failure modes. Methods are given for estimating the column strength of panels. Various forms of column curves and direct-reading charts are considered. Theory and test data on optimum stiffened panels are presented for use in preliminary design studies.

In box types of construction, the rib and spar structures influence the compressive strength of the stiffened panel. The various factors which can be of importance are considered.
