Abstract
The potential for structural instability in metal structures has been known since the famous paper of Leonard Euler in 1744 on column buckling. The constant challenge has been the desire to turn the excellent research worldwide in the area into design rules and specifications such as the Eurocodes, American Specifications, Japanese, Chinese and Australian Standards. New methods of stability analysis and design such as the Direct Strength Method (DSM) in the AISI S100 Specification and the Australian/New Zealand Standard AS/NZS 4600 for Cold-Formed Steel Structures have unified stability design across a range of buckling modes such as local, distortional and overall (Euler) buckling. Further, Advanced Analysis methods (often called GMNAI) which use the Finite Element Method (FEM) are being standardized for routine design of structural systems. The paper reviews these new methods, and their incorporation in design standards and specifications.
