讨论使用可变摩擦阻尼器的半主动结构控制方法。在所提出的算法中，仅响应第一模态坐标来控制摩擦阻尼器的滑动水平。更具体地，通过控制每个磁滞回线内的滑移水平来维持相对于第一模态响应的目标恒定延性因子。通过计算机模拟和比例模型实验证明了所提出的半主动控制的有效性。
Discusses a methodology of semi-active structural control using a variable friction damper. In the presented algorithm only the slipping level of the friction damper is controlled in response to the first modal coordinate. More specifically, the target constant ductility factor with respect to the first modal response is to be maintained by controlling the slipping level within each hysteresis loop. The effectiveness of the proposed semi-active control is demonstrated both by means of computer simulations and scale model experiments.
