Buckling of plates and plate girders subjected to patch load

Abstract

The determination of the elastic critical load (buckling load) is an important element of the assessment of the ultimate load of plate girders. An analysis of the critical load of a plate corresponding to the web of an I-girder for different boundary conditions and the critical load of the I-girder itself is given in the paper. Conclusions regarding their correspondence are given. Also, experimentally determined ultimate loads of I-girders are compared with values according to Eurocode for the models used in this analysis.
