Abstract
Structural members loaded by transverse loading in the plane of
greatest stiffness may fail before reaching the full plastic ultimate
load by lateral buckling. Steel thin-walled I-cross section plate
girders loaded by bending and shear are theoretically and
experimentally investigated. The results from the experiments of
16 girders are evaluated by the geometric nonlinear model of the
finite element method taking into account the geometric initial
imperfections and residual stresses as well. The concept of the
elastic critical load, the von-Karman concept, the CSN 731401
and the EUROCODE 3 are used for the evaluation of the load
carrying capacity. The rules for a practical use are prepared.
