The paper considers the elastic critical (buckling) load of steel I-girders subjected to patch loading in the plane of the web. The analysis of the influence of the load length and thickness of the flange on the elastic critical load of the girder without transverse and longitudinal stiffeners in the load application zone was performed. The buckling coefficients for the web of the I-girders were determined and compared with the values of the buckling coefficient of isolated clamped plates. Suggestions for improving the EN1993-1-5 patch loading resistance model are given.
Keywords:elastic critical load / buckling coefficient / patch loading
