Elastic buckling of web plates in I-girders under patch and wheel loading

The wheel load is another kind of patch load rarely touched in the literature. This paper suggests a simple model to determine the bearing stresses on the top edge of the web plates in I-girders where the effect of the crane rail rigidity is considered. Based on this model, the buckling of the web plate is analyzed and formulae with excellent accuracy are suggested to predict the buckling load.
