摘　　要：论述了采用悬挂水箱减小建筑结构在地震作用下反应的方法.利用悬挂水箱中液体的振动耗能和部分液体以及箱体的摆动耗能,减小建筑结构的地震反应.首先利用集中质量法,建立水箱———结构体系的计算模型和运动方程;然后根据水箱参数优化的结果,合理地选取了控制参数;最后进行3种地震作用下建筑结构的地震反应分析,并比较了控制的效果.研究结果表明,利用悬挂水箱中液体的振动和箱体的摆动,可以有效减小建筑结构的振动反应,为建筑结构被动控制技术提供了一种新方法.The method of using the Tuned Liquid Damper (TLD) to reduce the structure responses to earthquake ground motion is discussed in this paper. This method belongs to the passive control technology, which utilize the vibration of liquid in the pendulous tank and the swing of partial liquid to dissipate energy and to reduce the seismic responses. Firstly, the calculation mode and the equation of motion of tankstructure system are built by use of the centralization mass method; Then, the control parameters are chosen according to the result of the tank parameters optimization; Finally, the structure seismic responses under three kinds of earthquake excitations are analyzed, and the control effects are compared. The research results indicate that the vibration of the liquid in the tank and the swing of the tank can reduce the building structures vibration responses efficiently. A new method of passive control technology for structural seismic response control is put forward.
