ABSTRACT
A series of cold-formed steel lipped channel columns was conducted. A total of seventeen specimens with two of the repeated specimens was tested. The column specimens were compressed between fixed ends condition.The column test specimens were brake-pressed from high strength zinc-coated grades G500 and G550 structural steel sheets having nominal 0.2% proof stresses (yield stresses) of 500 and 550 MPa, respectively. These structural steel sheets conformed to the Australian StandardAS 1397 (1993).The nominal column length ranged from 1400 to 2750 mm. The test specimens had the nominal web width (bw) ranged from 53 to 88 mm, flange width (bf ) ranged from 48 to 88 mm and a constant lip width (bl) of 12 mm. The nominal plate thicknesses of the specimens were 1.0 and 1.2 mm.
