本文讨论了一系列试验的结果，以评估磁流变（MR）装置的性能，以减轻地震危害。剪切型磁流变阻尼器用于控制六层建筑在地面运动作用下的响应。采用多输入配置，其中两个阻尼器刚性连接在基础和一楼之间以及测试结构的一楼和二楼之间。采用基于加速度反馈的夹片最优控制算法确定控制动作。
This paper discusses the results of a series of experiments conducted to evaluate the performance of magnetorheological (MR) devices for earthquake hazard mitigation. Shear-mode MR dampers are used to control the responses of a six story building subjected to ground motion. A multiple-input configuration is used in which two dampers are rigidly attached between the base and first floor, and between the first and second floors of the test structure. A clipped optimal control algorithm that is based on acceleration feedback is used to determine the control action.
