The long-term load has great influence on the internal force distribution, deformation, bearing capacity and other mechanical properties of round-end concrete-filled steel tubular member. Parameter analysis is carried out on the influence coefficient kcr of the round-end concrete-filled steel tubular members under the influence of long-term effects. The parameter analysis results show slenderness ratio, concrete strength, steel content and load eccentricity have great impact on the influence coefficient kcr.
