| Abstract: | The paper describes the recently balloted Direct Strength Method (DSM) of design for shear of the North American Specification for Cold-Formed Steel Structural Members NAS S100. The method requires the shear buckling load Vcr of the complete section to be computed. Shear buckling examples of channel sections in pure shear using both the semi-analytical and spline finite strip buckling analyses are presented. Recent work on the buckling and strength of channel sections in pure shear with rectangular and triangular web stiffeners is also described. |
