Recently, there has been an increasing number of studies on the distortional buckling analyses cold-formed steel (CFS) channels with web edge-stiffened holes. However, literature about analytical solutions is scarce, and current design rules, e.g., American Iron Steel Institute (AISI 2016) Australian/New Zealand standards (AS/NZ 4600: 2018), provide little advice for CFS This paper presents met...

A pallet rack is a structure in which the beams and uprights are cold-formed steel sections. The beam-upright connections are normally clipped in order to select the beam levels required and for ease of assembly. For this reason, the uprights contain holes and perforations distributed along their length. The complexity of these components, with local, distortional and torsional/flexural bucklin...

The use of thin-walled structures has been increasingly spread in the last few decades due to their big advantages both structural design and construction methods. Therefore, recent researches have discussed a wide range applications. However, resistance such will be decreased by buckling effect; hence, different ways strengthening methods investigated. One this method is lightweight concrete a...
