讨论了一种采用变摩擦阻尼器的半主动控制方法。在这种变摩擦阻尼器中，只有滑移力水平是根据地面运动的震级来控制的，这样在任何地震事件中，阻尼器都应该表现出一种滞回，以耗散能量。所采用的控制算法比较简单，但效果很好。通过对某二十层建筑的计算机仿真，验证了该变摩擦阻尼器的有效性。然后利用系统辨识技术，利用等效阻尼系数对控制效果进行估计。
Discusses a methodology of a semiactive control strategy using a variable-friction damper. In this variable-friction damper only the slip-force level is controlled in response to the magnitude of ground motion in such a way that the damper should exhibit a hysteresis to dissipate the energy in any seismic event. The employed control algorithm is rather simple, yet quite effective. The effectiveness of such a variable-friction damper is demonstrated through the computer simulation applying the damper system to a twenty-story building. Then, the control effectiveness is estimated in terms of the equivalent damping factor by utilizing system identification technique.
