This work deals with the investigation on the behavior of cold-formed ferritic stainless steel hollow beams. The numerical model was developed by using Finite Element (FE) software ABAQUS . The developed FE model includes material non-linearity, geometric non-linearity and geometric imperfections. The numerical model is validated by comparison of experimental results reported by Afshan and Gardner (2013) . The sections for parametric study were selected based on the EN-1993-1-4 specifications . The key parameters varied in the study were material properties, section geometry and thickness of the section. The parametric study has been carried out by using the verified FE model and the results were compared with the flexural resistance predicted by the Direct Strength Method (DSM) . Based on the comparison of results the effect of geometric parameters on the cold-formed ferritic stainless steel hollow beams are discussed and based on the comparison of results the possible conclusions are drawn.
