Abstract

An approach to predict the direction and magnitude of the shift of the effective centroid of the cold formed steel structures was discussed. The shift of the effective centroid as predicted by the current design rules was shown to be accurate for plain channels but inaccurate for lipped channel with slender flanges. It was observed that the current design strength curve for lipped channel with slender flanges increased with increasing effective length. It was emphasized that in the design of pin-ended channel columns, it is necessary to account for the shift of the effective centroid caused by local buckling.
