The composition of the life-cycle cost (LCC) of TMD control device is analyzed and an optimal design method for TMD device is proposed based on cost-effectiveness criterion. The life-cycle costs and control effectiveness of the TMD system with different mass ratios are calculated, and then an analysis of the effectiveness-cost ratio of the TMD device is carried out. With the condition of meeting the specific performance requirements of the owners, the optimal parameters of the TMD system are obtained by using a performance index of the effectiveness-cost ratio, thus the best control performance is achieved with a low cost and the optimal saving of resources. Moreover, the LCC and the effectiveness-cost ratio of the control device are proposed to evaluate the effectiveness, economy and reliability of different vibration control strategies. The new Guangzhou TV Tower, highest structure in the world, is employed as an example, and the results show that the proposed method is efficient and of significance in practical applications.
