中文摘要：

本文将调谐液体阻尼器（TLD）和黏弹性阻尼器（VED）同时作用于结构，构成混合被动控制系统。通过对两类阻尼器分别进行优化设计并考虑两者间的相互影响，在充分发挥两者各自优良控制性能的同时，克服了VED大量使用导致控制系统整体造价过高的问题。算例分析表明，混合控制可以得到令人满意的整体减震效果，同时大大节约了VED用量，提高了控制系统的综合经济性能。

英文摘要：

Hybrid passive control system is established by using tuned liquid dampers （TLD） and viscoelastic dampers（VED）. Good control efficiency performed by TLD and VED can be obtained by the optimal design process. Meanwhile, the problem of too high cost caused by VED is overcome. Finally, an example shows that the satisfied control efficiency can be obtained by hybrid control system and the synthetical economical benefit is increased by saving the amount of VED.
