Purpose–Although the actual residual stress distribution in any structural steel member can
be only obtained by experimental measurements, it is known to be a difficult, tedious and …

The paper is devoted to cold-formed thin-walled channel beams with open or closed
flanges. The global–local buckling and optimization of these beams are described. The …

In this study, compressive strength, modulus of elasticity and steel tensile coupon tests are
performed to determine material properties. Sixteen hollow cold formed steel tubes and 48 …

This paper presents the experimental and numerical investigations into the structural
performance and strengths of G550 high strength cold-formed steel (CFS) lipped channel …

This study is focussed on the performance evaluation of built-up cold-formed steel (CFS)
columns under monotonically increasing axial compression loading. Five test specimens of …

A research study on the structural behaviour of cold formed steel beams with C-, I-, R-and
2R-shaped cross-sections at ambient temperature is presented, based on the results of a …

The current design methods for built-up back-to-back cold-formed steel (CFS) channel
compression members are considered inadequate despite several research studies in …

Built-up nested channel (NC) members, which are made of asymmetric cold-formed steel
(CFS) lipped channel sections are commonly used in various building applications in …

Built-up back-to-back cold-formed steel channel (BC) sections have gained increased
application as compression members in building structures. Although many researchers …

The current cold-formed steel (CFS) design standards have not yet provided adequate
design methods for built-up nested CFS channel compression members, which may fail by …
