Behaviour of cold-formed lipped C-channel with ferrocement jacket composite column under axial compression

One of the major challenges for strengthening or upgrading steel structures is to increase column capacity to withstand large expected loads. The main objective of the present study was to investigate the behaviour of build-up lipped Cold Formed steel (CFS) C-channel column assembled with ferrocemen...
