本文介绍了半主动阻尼器系统在实际建筑中的首次应用。半主动液压阻尼器（SHD）可以在70 W的电力下产生1000 kN的最大阻尼力。它结构紧凑，因此可以在一栋建筑物中安装大量的设备。本文介绍了该结构、控制系统结构、SHD、采用线性二次型调节器的控制方法、被控建筑物的反应分析结果以及实际SHD的动载试验结果。仿真分析表明，通过SHD控制可以防止建筑物在大地震中的破坏。本文报道了SHD的动载试验结果，表明其基本特性试验达到了设计要求。利用仿真响应时间历程进行的控制性能测试也表明，阻尼力与指令吻合良好。最后，它被证实，半主动阻尼器系统应用于实际建筑有效地控制其在强烈地震反应。版权所有© 1999年约翰威利父子有限公司。
This paper presents the first application of a semi‐active damper system to an actual building. The Semi‐active Hydraulic Damper (SHD) can produce a maximum damping force of 1000 kN with an electric power of 70 W. It is compact, so a large number of them can be installed in a single building. It is thus possible to control the building's response during a severe earthquake, because a large control force is obtained in comparison with a conventional active control system.This paper outlines the building, the control system configuration, the SHD, the control method using a Linear Quadratic Regulator, the response analysis results of the controlled building, and the dynamic loading test results of the actual SHD. The simulation analysis shows that damage to buildings can be prevented in a severe earthquake by SHD control. The dynamic loading test results of the SHD are reported, which show that the specified design values were obtained in the basic characteristic test. The control performance test using simulated response time histories, also shows that the damping force agrees well with the command. Finally, it is confirmed that the semi‐active damper system applied to an actual building effectively controls its response in severe earthquakes. Copyright © 1999 John Wiley & Sons Ltd.
