Where a full-length stiffener is required to resist web buckling, then the design is performed according to specification 4.5.2.3. The "stiffener column" dimensions are calculated as prescribed in these sections. The smaller of the column design yield strength and the stiffener nominal yield strength is used to perform the check according to 4.5.2.3. Refer to the technical notes and the joint criteria section for more information on the stiffener design.
