Abstract: This paper describes a study of the behaviour of cold-formed high strength steel angles. Thirty-six specimens with
different cold-formed angles (90°, 100°, 120°, 140°, 160°, and 170°) and different thicknesses (4 mm and 6 mm) were
considered. The initial geometric imperfections of the specimens were determined using the 3D laser scanning method.
The magnitudes of these geometric imperfections for torsional and torsional-flexural buckling and flexural buckling
analyses were proposed. The commercial finite element analysis (FEA) programme ABAQUS with shell elements S4R
was used for finite element analyses. Different material strengths in corner and flat parts along with different proof
stresses (0.2%, 0.01%, and 0.006%) were considered in the numerical models. The experimental and FEA results showed
good agreement. Influence of cold-formed angle on non-dimensional slenderness and reduction factor curves of the 4 mm
thick columns with 90° and 120° cold-formed angles was analysed.
