There are several methods to cover the interaction of compression and bending for slender steel members. Usually an interaction formula is given and more recently also the general method can be used in terms of more advanced global analysis. In respect to stainless steel, the structural design standards have been developed largely based on the carbon steel standards. The current formula for interaction of axial force and bending moment given by EN 1993-1-4 was derived on limited results available and there is no limitation for the general method in the standard despite the non-linear stress-strain behaviour of stainless steels. Therefore the main aim of the paper is to show and compare numerical results for stainless steel beam-columns with existing Eurocode, the general method and some formulae proposed by other researchers taken from experimental and parametric studies. Their possible applicability will be shown as well as the way for further development. The conclusions may be used for other non-linear materials too, such as aluminium alloys, to some extent.
