European alternatives to design perforated thin-walled cold-formed beam–columns for steel storage systems

Distortional buckling of perforated cold-formed steel channel-section beams with circular holes in web

“…The influence of web opening on the lateral-torsional buckling behaviour of CFS channel-section purlins was also examined by Ling et al [18] using finite element method. More recently, extensive research has been carried out on the load bearing capacity of rack uprights subjected to combined axial and bending loads using different analysis methods, including design codes [19], experimental [20] and finite element numerical [21][22][23] methods.…”

European design approaches for isolated cold-formed thin-walled beam–columns with mono-symmetric cross-section

“…2 but also for all structural systems made by mono-symmetric (solid) members. No attention has been paid to the design of perforated uprights, which has been investigated in a separate study [66].…”

Local Plastic Instabilities of Perforated Thin-Walled Bars – FEM Modelling and DIC Verification

“…Storage systems are one of the most popular applications of perforated thin-walled bars, but the design rules for such systems can give results on the unsafe side [1], leading to many dangerous situations (structure failures) and financial losses. The paper presents results of experiments and numerical modelling of compression tests of elements presented in Fig.1.…”
