- •
The compressive local–overall flexural response of plain channel columns is determined.
- •
Local form change during compressive loading is shown to promote column deflections.
- •
End support conditions are shown to significantly influence global column behaviour.
- •
For local rotational restraint, column deflections occur from the onset of local buckling.
- •
The locally rotationally free condition; permits a straight column after local buckling.
