Since the steel skin confines the filled-in concrete tri-axially and the concrete resists against the inward deformation of steel skin, both steel and concrete contribute to the strength enhancement of the CFT column. The CFT columns are susceptible to local buckling of the steel skin, which in many cases is very thin.
