Built-up box sections are becoming increasingly popular for column members in cold-formed
steel (CFS) construction; uses of such sections include CFS trusses, space frames, and …

Local buckling is a failure mode commonly observed in thin-walled structural steel elements.
Even though its effect on their behaviour at ambient temperature conditions is well …

Built-up box sections are gaining popularity as column members in cold-formed steel (CFS)
construction. Applications include CFS trusses, space frames, and portal frames. Two …

Cold-formed steel (CFS) built-up sections are widely used to achieve adequate load-bearing
capacity when individual shapes are not able to resist the design loads. In the existing …

This paper investigates the post-buckling behaviour and axial capacity of thin-walled steel
stiffened single-channel sections (ISSCS) and back-to-back stiffened channel sections …

This paper reports on experiments addressing the buckling and collapse behavior of an
innovative built-up cold formed steel (CFS) columns. The built-up column consists of four …

Built-up cold-formed steel (CFS) studs, such as back-to-back channels (BC) and nested
channels (NC) are used in light gauge steel framed (LSF) wall systems instead of the …

Concrete-filled composite columns are widely used in the construction industry, exploiting
the benefits of combining steel and concrete, providing, for instance, high load-bearing …

Screwed connections are commonly used in fabricating built-up cold-formed steel (CFS)
members. However, the knowledge and understanding of their behaviour and design are …

Box-shape cold-formed steel built-up columns (CFS-QBC) are popular in multi-story CFS
buildings. This paper conducted experimental research, numerical simulation, and …
