Abstract: Abstract This paper describes a test campaign concerning the behaviour and strength of cold-formed steel (CFS) lipped channel (LC) beams experiencing local-distortional (L-D) interaction made of G450-G500 high-strength steel grades. This investigation involves the performance… read more here.

DOI: 10.1016/j.tws.2017.08.014
Abstract: Abstract In this work, the development of rational explicit equations for distortional buckling critical stress of lipped channel columns subject to uniform compression is presented. An energy-based approach is adopted along with two different assumed… read more here.

DOI: 10.1016/j.tws.2018.07.031
Abstract: Abstract The ultimate buckling strength of axially loaded cold-formed lipped channel columns is studied. Variations of boundary conditions and eccentricities of the applied load are considered. The strength is calculated by a geometrically and materially… read more here.

DOI: 10.1016/j.tws.2019.106265
Abstract: Aluminium alloys have recently drawn significant attention in structural applications due to its outstanding mechanical characteristics. Thin-walled members fabricated by aluminium alloys can be more competitive in construction industries than the conventional cold-formed steel sections,… read more here.

DOI: 10.1590/1679-78256264
Abstract: BUCKLING MODE INTERACTION IN COLD-FORMED STEEL (CFS) MEMBERS MUST BE CONSIDERED FOR THE STRUCTURAL DESIGN, SINCE THE MODAL INTERACTION MAY LEAD TO A SIGNIFICANT REDUCTION OF THE STRUCTURAL STRENGTH, USUALLY RECOGNIZED AS EROSION OF THE… read more here.
