An axially compressive thin-walled steel element on elastic foundation is adopted to deduce the critical stress and critical diameter to thicknessratio for circular steel tube in local buckling.
Calculation for short columns using Grade Q235 steel tube filled with Grade C30 concrete indicates that the critical diameter to thicknessratio of steel tubes is about 1700.
