摘要：
The tuned liquid column damper(TLCD), is a cost-effective passive device to increase the structural damping. The design method for TLCD was evaluated. The most efficient placement for the absorber was determined in accordance with the dynamic characteristics of the structure. The optimum geometric parameters were analysed based on the equation of motion. The optimal frequency and damping with respect to a selected mode of the structure were simplifiedly achieved by comparing with the TMD tuning with the properly transformed Den Hartog's optimal parameters. Finally, the design procedure was gained. The numerical simulation of a 30-storey plane-asymmetric structure illustrates the effectiveness of TLCDs to mitigate the earthquake induced vibrations of plane-asymmetric buildings, and also the feasibility of the proposed method. © 2018, Editorial Office of Journal of Vibration and Shock.
