Resume Simplified formula of the web slenderness limit given in EN 1993‐1‐5 to prevent the flange‐induced buckling does not usually govern the web design other than very slender Class 4 plate girder webs in steel S235 to S355. However, the same formula applied to plate girders designed in HSS S690 gives lower slenderness limits likely to govern web's design and restrains the possibilities of reducing their thickness. This paper reviews the background of the simplified formula currently used and compares the web slenderness limits obtained with numerical results from full nonlinear analysis of slender high strength steel girders.
