Abstract
The results of an investigation on the web crippling strength of cold-formed, stainless steel channel sections are presented in this paper. The stainless steels under consideration are AISI Types 304, 430 and a modified Type 409, designated Type 3CR12 corrosion-resisting steel. The lipped channel sections were manufactured by a press braking process. Beams were tested in pairs, lips facing, in an exterior-one-flange loading configuration. Experimental results were compared with the theoretical predictions given in the 1991 edition of the Specification for the Design of Cold-Formed Stainless Steel Structural Members. It was concluded in this study that the experimental results compare reasonably well with the theoretical predictions. For longer bearing lengths the theoretical strengths appear to be conservative.
