The strength and ductility of concrete will dominate structural performance under expected rare earthquake, and concrete filled steel tube is an effective solution for this goal in super high-riseÿbuildings. As reliable numerical simulation of these kinds of structures may depend on reasonable constitutive relationship, two typical constitutive models are analyzed in this paper, and they are also being compared with the constitutive relationship of plain concrete for equivalent Young's modulus and the initial stages of skeleton curves. The results show that these two models all can embody the confining effect of steel tube, but they are not suitable for low-stress state and modal analysis.
