Abstract
AbstractSupaCee section is formed by adding stiffeners in the web of the channel section, and it has been illustrated to be more stable and innovative than the traditional channel section. The member capacity comparisons between such two section members investigated in a companion paper showed that SupaCee was significantly beneficial for small and thin section members, but the reductions of global buckling strengths of SupaCee section members led to the lower capacities for long members compared to those of channel section members. These reductions can be prevented by using full bracing systems to avoid global buckling; this allows member capacities to reach sectional capacities. This paper, therefore, presents a study on sectional capacities of cold-formed steel SupaCee sections under compression or bending in comparison with those of channel sections.
