The Erosion of Critical Bifurcation Load (ECBL) approach is a practical tool to characterize the instability behaviour of thin-walled cold-formed steel members. In this framework, the Generalized Beam Theory (GBT) is used to find (1) the interaction point of simultaneous buckling modes and (2) the erosion of the critical bifurcation load referred to this interactive buckling of two or more buckling modes associated with the same critical load. In this sense a modified version of the ECBL approach is proposed. Some numerical re-sults involving pallet rack uprights in compression are presented and compared with experi-mental ones, classical ECBL approach and EN 1993-1-3.

Abstract

The Erosion of Critical Bifurcation Load (ECBL) approach is a practical tool to characterize the instability behaviour of thin-walled cold-formed steel members. In this framework, the Generalized Beam Theory (GBT) is used to find (1) the interaction point of simultaneous buckling modes and (2) the erosion of the critical bifurcation load referred to this interactive buckling of two or more buckling modes associated with the same critical load. In this sense a modified version of the ECBL approach is proposed. Some numerical re-sults involving pallet rack uprights in compression are presented and compared with experi-mental ones, classical ECBL approach and EN 1993-1-3.
