ABSTRACT:
The invention concerns the use of actively tuned liquid dampers to quench vibrations in large civil structures. Such vibrations may be induced by earthquakes or high winds. The effective length of the liquid damper tank determines the natural frequency of the liquid, and thus the effectiveness of the damper at particular excitation frequencies. The liquid damper is tuned by rotating baffles to regulate the effective length of the damper tank.
