Abstract: Cold-formed steel (CFS) sections are commonly applied to modern engineering structures, such as roof truss, purlin and industrial goods rack. This study proposes an analytical model to investigate the distortional buckling behavior of CFS-lipped channel… read more here.

Abstract: Abstract Usual design practice for distortional buckling considers a lower bound solution as the actual buckling load. In reality, this practice is inconsistent with actual case since the obtained buckling load is a constant value… read more here.
