AISI-Specifications for the Design of Cold-Formed Steel Structural Members

Alternative Title

Research report RP02-2

Abstract

A new web crippling design approach has recently been adopted by the American Iron and Steel Institute and the North American Specification for the Design of Cold-Formed Steel Structural Members, November 9, 2001 Draft Edition (NAS, 2001). The current web crippling and bending interaction equations for single-web sections in the Specification (NAS, 2001) are based on the previous web crippling methods. As well, the moment component of the interaction equations was based on the previous reduced web strength method instead of the stress gradient approach that is now contained in the Specification (NAS, 2001). Based the available data found in the literature, regression analyses were carried out using the new web crippling equations and the stress gradient method to substantiate the current web crippling and bending interaction equations in the Specification (NAS, 2001). Based on the results of this investigation, new web crippling and bending interaction equations have been developed.
