Buckling tests were conducted on concrete filled tube using high tensile strength steel and high strength light-weight concrete. The test results showed that the increase of axial load bearing capacity of the light-weight concrete due to the effect of confinement is not expected even if slenderness is low, and that it is possible to evaluate the buckling strength in current methods if only the effect of confinement is ignored.
