Abstract (en)
[origin: EP0686733A1] The equipment is esp. for chimneys, masts, industrial tanks etc. with quasi-rotational-symmetrical-vibration characteristics. It comprises a liquid-filled tank whose weight, sloshing frequency and inherent damping characteristics are matched to the natural frequency of the building. The distance (A) from each enclosing wall (W) of the tank to the mid-point (M) of the surface of the liquid at the central perpendicular is approximately the same. The height to which the tank is filled can be less than the distance (A), and typically less than half of it. The tank may be square or can have a circular bottom (G), or it can be annular and divided by radial partitions. <IMAGE>
