Abstract

Abstract

Based on twin shear unified strength theory, the contributions of steel tube, web, concrete in the steel tube and cavity and constrains provided by steel tube and web were considered.Whilst considering the influence of slenderness ratio, eccentricity ratio and initial stress for dumbbell shaped cross-section, the ultimate bearing capacity formula for dumbbell shaped concrete-filled steel tubular column was developed by two methods, and the impacts of some relevant parameters were analyzed as well.Through comparing the results of proposed formula with that of experiments and relevant literatures, the rationality of proposed formula was proved.
- unified strength theory,
- dumbbell shaped,
- concrete-filled steel tubular column,
- ultimate bearing capacity
