Strength curves for web crippling design of cold-formed stainless steel hat sections,

The web crippling design guides are based on empirical adjustments of available test data. These equations differ from the basic concept underpinning most of the other instabilities, the so-called strength curves. This investigation presents a new design approach for web crippling design of stainless steel hat sections based on strength curves controlled by slenderness-based functions  (View the MathML source). The effects of web crippling on such cross-sections were studied numerically and the obtained results were used to derive the design expressions.
