N2 - This paper presents an experimental investigation of the compressive resistances of starred cold-formed lipped angles under simple end conditions. Two sizes of lipped angles, 75 × 50 × 20 and 100 × 75 × 20, were tested, with varying thickness from 2.0 to 3.0 mm. The lengths were chosen to be 873 and 1873 mm to cover the two extreme behaviour of columns of yielding or local buckling of the cross-section and overall flexural, torsional or torsional-flexural buckling. As anticipated, the compressive resistances of the starred angles decreased with an increase in length, and increased with increase in thickness. The short columns failed by local buckling and the longer columns failed due to either overall flexural, torsional or torsional-flexural buckling. The average compressive resistance of the columns were then compared to the code-predicted buckling strength, calculated using SANS 10162-2:2011 (AS/NZ 4600:2005).
