Evaluation of the Flexural Strength of Cold-formed Steel Studs with Embossed Flanges

Abstract

New advances and improvements in the manufacture of cold-formed steel shapes are continually being made. One such advancement in the manufacturing of steel studs is flange embossing, a technique used to facilitate the installation of drywall screws into the stud flange. Currently, embossed flanges are not specifically addressed in the North American Specification for the Design of Cold-Formed Steel Structural Members (AISI S100), thereby drawing into question the use of current design equations from being used to calculate member properties for an embossed stud. a limited experimental investigation was undertaken to determine if light flange embossing affects the nominal flexural strength of cold-formed steel studs. Studs with embossed flanges were tested in bending and their actual flexural strength was determined. This data was then compared with the nominal flexural strength without embossing calculated using AISI S100-07 equations. the findings indicate that light flange embossing does not adversely affect the bending strength of the stud either negatively or positively and therefore, based on the scope of this study, the equations in AISI S100-07 for nominal flexural strength can be applied to lightly embossed studs.
