摘　　要：本文用阻尼器控制高层建筑水平地震反应,为此进行了理论分析及模型试验研究。文中首先提出一种有效的被动控制措施——阻尼筒控制系统,它构造简单、安装方便、实用性广。阻尼筒控制系统具有显著的阻尼水平,使得施加阻尼筒控制的高层建筑具有非比例的阻尼分布,在地震反应分析中,建立了一种子空间复模态时程分析法,有效地改善了复模态方法的实际应用。在数值模拟研究中,对阻尼筒控制系统的阻尼参数及其在建筑上的安装位置进行了优化分析,能使高层建筑的水平地震反应达到了理想的控制效果。最后在振动台上对一个三层框架建筑模型进行了试验研究,进一步验证了所取得的研究成果。In this paper,the damper control is applied to the horizontal seismic responses of multistorey buildings,and the theoretical analysis and experimental research are performed. Firstly, an efficient passive control measure -the damper tube control system is proposed,which is of simple construction,convenient installations on buildings and wide practical applications. The multistorey buildings with damper tube control systems possess non - proportional damping distribution due to the striking levels of damping of the damper tubes. In the seismic analysis,a subspace complex modal history algorithm is built,which efficiently improves the practical procedure of the complex modal methods. In the numerical simulated investigation, the damping factors of the damper tube control systems and their placements on buildings are optimally analyzed so that a realized control effect can be obtained. Finally,the experimental research for a model of 3 -storey frame building on the shaking table furtherly proves the theoretical results in this paper.
