The studies on crippling of rolled beams and plate girders' webs, subjected to patch or distributed edge loading, summarized in this report. Solutions are available for the elastic critical buckling loads of idealized web panels which show little or no correlation to crippling loads determined from tests. Semi-empirical formulae are available to predict the crippling load with an accuracy that is acceptable for practical purposes. Formulae to predict the crippling load are recommended. Semi-empirical formulae to predict loads above which membrane yielding of the web becomes pronounced are also available. The effects of coexistent global bending moment or shearing force were discussed. Reduction of P sub u due to coexistent global moment has been established by the way of a formula for a reduction factor. A conservative approach is recommended. The requirements to prevent crippling given in the AISC building specification, as well as the proposed AISC LRFD specification, have to be reexamined in the light of the information in this report.
