摘　　要：将深水调谐液体阻尼器(TLD)作为以单一振型反应为主的建筑结构地震荷载作用下的被动减震装置,通过建立并求解TLD参数优化设计目标函数,得到最优参数实用设计表达式.同时,引入了结构-TLD系统等效阻尼比概念,给出了相应于TLD最优设计参数的等效阻尼比设计表达式.最后通过数值算例,验证了等效阻尼比表达式的适用性.A deep water tuned liquid damper （TLD） is used as a passive control device for reducing a dynamic response of structure whose responses are dominated by a single model under earthquake load- ing. The practical equations for the optimal parameters of the TLD are obtained by formulating the ob- jective function of the TLD＇s optimum parameters. Meanwhile, equivalent damping ratio of structure- TLD system is introduced and the equations of the equivalent damping ratio with respect to the opti- mum parameters of TLD are presented. Finally, the applicability of the equations for the equivalent damping ratio is verified by numerical examples.
