Abstract: An active liquid damper as a device for damping vibrations of structures under transient (seismic) influences is considered. The operating principle consists of alternating reactive force formation resisting to relative (flexural) displacement (oscillatory movements) of the structure. The results of the numerical experiment conducted to evaluate the damper efficiency, the choice and settings adjustment are analyzed. The comparison of the liquid reactive damper with the passive three-mass dynamic vibration damper is carried out. According to the results of this comparison, the conclusions about the given dampers efficiency are drawn.
