Comparative analysis of patch loading buckling resistances according to existing and new Eurocode

Summary: This paper compares the procedures for calculating steel plate girders according to thе current standards ЕN1993-1-5: 2006 [1] and the new version prEN1993-1-5: 2020, which is in the final stage of development [2]. There is a particular emphasis on problems of resistance to patch loading, the interaction between transverse force, bending moment and shear force, and the reduced stress method. The differences between the current standard and the new version prEN1993-1-5: 2020 [2] are illustrated using specific numerical examples.
