Buckling of coped steel beams and steel beams with partial endplates

Copes and partial endplates influence the resistance to lateral buckling of a steel beam. In order to quantify this influence, numerical research has been carried out with validated models. Full-scale laboratory tests carried out for the validation of the numerical models are described in the Annex to this paper. The research resulted in proposed reduction factors for the critical elastic buckling load of beams with various end connections. With the reduced elastic buckling load and the existing buckling curves the resistance of steel beams with copes and partial end plates can be determined.
