Unstiffened Strip Approach for Perforated Wall Studs
Publication: Journal of Structural Engineering
Volume 120, Issue 2
Abstract
Local buckling behavior of cold‐formed steel wall studs with rectangular web perforations is investigated experimentally and analytically. Stub column tests on short sections not subject to overall buckling are examined. The unified effective width approach to local buckling presented in the 1986 Specification for the Design of Cold‐Formed Steel Structural Members of the American Iron and Steel Institute (AISI) is modified to model the perforated section. The web is idealized as two unstiffened elements extending the length of the member. In addition, the current AISI stub column‐based empirical approach and a “simplified” method used by some designers are examined. In the simplified approach, perforation effects are ignored unless the perforation is located in a portion of the web that is at least partially effective. Comparisons made between predictions of post‐buckling strengths using the unstiffened strip approach and the stub column test results show the unstiffened strip model to be a useful design methodology.
