Analysis for local buckling capacity of cold-formed steel sections with web opening

ADINA finite element solutions for the local buckling behaviour of C-shaped lipped channel cold-formed sections, with and without a large web opening, subjected to concentric axial load are presented. Isoparametric shell elements are used to model one-quarter of the sections. The web opening is generated using element birth/death option. The cold-formed steel has been treated as multi-linear elastic-plastic material with von Mises yield …
