Abstract

This paper presents the yield line mechanism analysis on web crippling of cold-formed stainless steel square and rectangular hollow sections under two-flange loading conditions. Two-flange loading conditions of End-Two-Flange and Interior-Two-Flange as specified in the American Specification and Australian/New Zealand Standard for cold-formed stainless steel structures have been investigated in this study. In addition, the end loading condition, where the test specimens were seated on a fixed flat solid base plate, which is not specified in the specifications, is also investigated. Three design procedures to predict the web crippling strengths of cold-formed stainless steel tubular sections, based on the failure mode but using different assumptions, have been considered. Two of the web crippling design procedures were theoretical derived using yield line mechanism analysis, and one design procedure was derived through a combination of theoretical and empirical analyses. The web crippling test strengths were compared with the design strengths obtained using the three design procedures.
