Abstract: To study the mechanical behavior of conical double skin steel tubes confined concrete stub columns subjected to axial partial compression, it was set up a finite element analysis(FEA) model and the predicted performances were validated through measured results.Based on the finite element analysis, the interaction between steel tube and sandwich concrete, failure mode, as well as the effect of the main parameters on the load-displacement was analyzed. -
