Local and Distortional Buckling of Cold-Formed Steel Members
Laminar structures have a high post-buckling strength reserve. Cold-formed steel profiles can be taken as a set of thin plate elements. Therefore it is necessary to design this type of profiles taking into account that reserve of strength in post-local buckling modes of failure. The method normally used to design this type of structures is based on the Effective Width concept. The Effective Wid...
متن کاملLocal Buckling Tests on Cold-Formed Steel Beams
C and Z sections are two of the most common cold-formed steel shapes in use today. Accurate prediction of the bending performance of these sections is important for reliable and efficient cold-formed steel structures. Recent analytical work has highlighted discontinuities and inconsistencies in the American Iron and Steel Institute ~AISI! and Canadian Standards Association ~S136! design provisi...
متن کاملDesign of Cold-Formed Steel Screw Connections with Gypsum Sheathing at Ambient and Elevated Temperatures
Abstract: Load-bearing cold-formed steel (CFS) walls sheathed with double layers of gypsum plasterboard on both sides have demonstrated good fire resistance and attracted increasing interest for use in mid-rise CFS structures. As the main connection method, screw connections between CFS and gypsum sheathing play an important role in both the structural design and fire resistance of this wall sy...
متن کاملDistortional Buckling Tests on Cold-Formed Steel Beams
Failure in cold-formed steel beams is generally initiated by one of three instabilities: local, distortional, or lateral-torsional buckling. For cold-formed steel joists, purlins, or girts, when the compression flange is not restrained by attachment to sheathing or paneling, distortional buckling may be the predominant failure mode. Experimental results on cold-formed steel beams with unrestrai...
متن کاملYield - line analysis of cold - formed steel members
The objective of this paper is to provide a state of the art review of the application of yield-line analysis to cold-formed steel members, and present a newly developed solution to the stresses that develop in an inclined yield-line. Yield-line analysis in cold-formed steel members is shown to be distinct from traditional yield-line applications. Challenges in the application of yield-line ana...
