This paper, therefore, is aimed to evaluate the capacities of SupaCee sections by comparing them with the capacities of the traditional channel sections under compression, bending or shear. The investigated SupaCee and channel sections are taken from the available commercial sections. The capacities of the investigated sections and members are determined according to the Australian Standard AS/NZS 4600-2018, and the material properties are regulated in Australian Standard AS 1397. The investigated results are the basis to evaluate the innovation in strength improvements of SupaCee sections in comparison with those of channel sections under compression, bending or shear.
