Cold formed steel members are new compared to hot rolled material in building construction. Mostly all cold formed elements have open cross sections and the thicknesses of its members are normally small related to their widths. Therefore, local buckling may occur before the section yields. The work presented is based on experiments of axially compressed cold formed folded plates with two different plate thicknesses of 6 mm and 8 mm; for thickness of 6 mm with two different lengths, 400 mm and 900 mm and for 8 mm plate thickness with a length of 400 mm. A nominal steel grade of S355 is used in experiments. The results, carried out in experiments, are compared to Finite Element Analyses (FEA), taking into consideration different yield strength in the cold-formed areas. The commercial software ABAQUS is used and the validity of rules of EN 1993 part 1-3 is checked.
