Abstract
The goals of this study are to understand differentbuckling modes, determine the buckling mode and maximumbuckling capacity of the built-up C-channels, and evaluate theAISI-2001 Specification. For these goals, the following wasconducted: 1) different buckling modes of cold-formed steelcolumns were investigated; 2) previous research on built-upcolumns and testing rigs for column buckling was reviewed;and 3) the authors’ buckling test results of 42 cold-formedbuilt-up columns were examined. The study and review helpbetter understanding of the buckling modes and the effect ofdesign or testing parameters on the buckling behavior. Theresults show inconsistencies in the calculated values byAISI-2001 as compared to the maximum capacity loadsdetermined from the buckling tests. The orientation of themember substantially impacts the maximum load of themember.
