摘　　要：研究在地震激励下,环形调液阻尼器(CTLCD)对结构扭转反应的振动控制作用。首先建立起环形调液阻尼器在地震作用下的运动方程,采用随机振动理论,导出了在地震作用下环形调液阻尼器振动控制的最优参数。对结构纯扭转的振动问题进行研究,分析了控制系统各参数对控制后结构等效阻尼比的影响。对结构扭转耦联的振动问题进行研究,分析了控制系统各参数对结构平移等效阻尼比和扭转等效阻尼比的影响。结果表明,环形调液阻尼器是一种有效的扭转振动控制装置。The control performance of Circular Tuned Liquid Column Dampers (CTLCD) to torsional response of structure excited by ground motions is investigated. Based on the motion equation of the CTLCD-structure system, the optimal control parameters of CTLCD are given through some derivations supposing that the ground motion is a stochastic process. The influence of systematic parameters on the structural equivalent damping ratio is analyzed for purely torsional vibration. The effect of systematic parameters on the structural equivalent damping ratio in translational and torsional direction is studied for torsionally coupled vibration. The results show that the Circular Tuned Liquid Column Damper (CTLCD) is an effective torsional response control device.
