Recently, there have been some cases of the damage or collapse of the self-standing steel-tube structures due to dynamic loads. Tuned Liquid Column Damper (TLCD) is a tuned absorber which is very suitable for vibartion control of these stuctures. This paper focuses on the application of TLCD in self-standing steel-tube structures. The configuration of the ring shape TLCD is introduced firstly, and its mechanical model is deduced. Then the dynamic equation of the self-standing steel-tube structure with ring shape TLCD is established. According to the experimental model of a self-standing steel-tube structure, a ring shape TLCD is designed for the experiment, and both the loading and testing schemes are confirmed. A model updating method based on Simulated Annealing algrithm is proposed for the self-standing steel-tube structures, and the numerical case study is also conducted. In the study, the design variables are the base rotating stiffness and stiffness modification factor, and the objective are the first three frequencies tested. The maximal error of these frequencies of the updated numerical model is only 1.74%. Lastly, the vibration control experiment for the structure with ring shape TLCD is conducted, and by using the updated model, the results of the experiment are compared and discussed. The investigation shows that the ring shape TLCD used in this experiment can increase the equivalent damping ratio of the self-standing steel-tube structure from 0.0134 to 0.0267, so the dynamic response may be reduced effectively. And the programme can predict the dynamic responses of the self-standing steel-tube structures with ring shape TLCD in some degree. Both the numerical analysis method and the dyamic experiment may offer some reference for the design and application of the ring shape TLCD used in the self-standing steel-tube structures.
