Abstract: The effects of local buckling on the behaviour and load carrying capacity of thin-walled cold formed steel plain channel sections is examined. The bending is applied in such a way that the unstiffened flanges comprise the bending elements. Test results show that under these circumstances the unstiffened elements are significantly better in load carrying capacity than current cold formed steel design specifications suggest. It is also found that even quite slender unstiffened elements can withstand loading into the plastic range before failure. An approach to the design analysis of these sections is suggested and shown to give results which are in reasonably good agreement with experiment.
