Experimental Study on Compressive Behaviour of Cold Formed Corrugated Steel Section

The cold formed steel section vastly used as secondary member. In this paper focused on it is used as primary compression member. Cold-formed steel sections are usually formed in channel sections, Z-sections, hat sections, angle sections and other sections due to the manufacture process, and these sections are categorized as open sections. These sections can be also formed by connecting two or more sections together, for examples, an I-section formed by connecting two channel sections back-to-back, and a box section formed by connecting two channel sections in the flanges. Thickness of the section is 2.5mm and length is 800mm. These sections may fail by local buckling due to their short length. However, cold-formed steel sections can be strengthened by forming edge and web stiffeners in the I-shaped sections. Moreover providing spacing 25mm between two channels. Ultimate load is predicted from ABAQUS then it is compared with experimental result. Therefore, the focus of this study is to investigate the cold-formed steel I-shaped open sections with edge and web stiffeners.
