The concrete confinement, which depends mainly on the ratio of the external diameter of the steel tube to the plate thickness, the yield stress of the steel tube and the unconfined compressive strength of the filled concrete, is empirically deduced. A comparison with the experimental data published in the literature indicates that the present method provides more efficient representation of the ultimate strength of circular CFT stub columns than the existing codes, such as ACI-2005, AIJ-2001, Eurocode-2004 and DL/T-1999.
