Sub-zero temperature behaviour of cold-formed steel members
Cold-formed steel (CFS) industry has opportunities to expand the use of CFS in sub-zero temperature environments, such as Arctic and Antarctic regions, large scale refrigeration facilities and off-shore structures. Although the behaviour of hot-rolled steel members in such environments has been inve...
