Load capacity of axially loaded column of cold-formed steel structure

The axial load capacities of the compression members are often controlled by local and distortional buckling, buckling modes can be to a substantial reduction in the load bearing capacity of these members. The current tendency towards deeper, more slender sections makes this stability problem even more critical. The current methods for calculating the axial load capacity of Cold-formed steel C-channel section columns is based upon experimental studies conducted different web and flange dimensions and 300 mm long. The results of full-scale testing collapse loads were compared to theoretical capacities of the current AISI and EC3. This study is based on theory and experimental data which has been carefully analyzed and complied with this study. The results obtained from the experiment are compared with the analysis. In this study, the un-lipped and lipped columns analyzed using the EC3 and the AISI standards investigated which standard is more conservative. Finally, a suitable conclusion has been made and utilized in this thesis.
