本文对高层建筑地震反应进行优化阻尼器控制研究。文中首先简述了阻尼器控制的原理，提出了便于实际应用的阻尼筒控制系统。由于阻尼控制器的显著阻尼水平，使得建筑具有非经典阻尼分布，因而采用复模态方法进行模态分析，研究了阻尼控制器的参数及其在建筑上的安装位置对建筑复模态的影响。在地震反应分析中，提出了子空间复模态时程分析方法，有效地改善了复模态方法在非经典阻尼结构地震反应分析中的应用。对阻尼器的阻尼参数进行了优化分析，并对一个８层建筑的地震反应施加阻尼器控制，结果表明，优化阻尼器控制显著地降低了建筑的地震反应。
This paper studies the optimization of damper control for seismic response of high-rise buildings. Firstly, the principle of damper control is briefly described and a damper cylinder control system that is convenient for practical application is proposed. Due to the significant damping level of the damping controller, the building has a non-classical damping distribution. Therefore, a complex modal method is used for modal analysis. The influence of the parameters of the damping controller and its installation location on the building to the complex modal state of the building is studied. . In seismic response analysis, a subspace complex modal time history analysis method is proposed, which effectively improves the application of the complex modal method in seismic response analysis of non-classical damped structures. The damping parameters of the damper were optimized and analyzed. A damper control was applied to the seismic response of an 8-story building. The results showed that the optimized damper control significantly reduced the seismic response of the building.
