This paper summarises and presents main results of an in-depth numerical analysis dealing with the shear buckling resistance of stainless steel plate girders. The studies conducted have permitted the development of a simple design expression to determine the critical shear buckling stress in steel web panels. This expression takes into account the effects of the material nonlinearity together with the actual boundary conditions of the web panel given by the geometry of the plate girder by two defined parameters: ηη and krss, which is the shear buckling coefficient. Expressions given to obtain ηη will quantify mainly the effect of the material nonlinearity whereas the proposed analytical expression of krss will reproduce principally the influence of the real boundary conditions in a web panel.
