The present study undertakes the post-fire stub column behaviour of cold-formed steel
elliptical hollow sections (CFS-EHS) by experimental and numerical analyses. A total of 18 …

Numerous experiments have been conducted to investigate the mechanical properties of
structural steels at elevated temperatures, including mild steel and high strength steel (HSS) …

This study deals with the compressive performance of cold-formed steel semi-oval hollow
section (CFS-SOHS) stub columns after exposure to a standard fire. An experimental …

Cold-formed steels (CFS) or light gauge steels (LGS) are steel sections created through
processes without heat application, such as roll forming or press-braking. In the past few …

Due to the harsh working conditions and high cost of data acquisition in the actual
environment of modern rolling mills, the resulting limited datasets issue leading in …

A numerical investigation is conducted on the local buckling behavior of cold-formed square
