Abstract: The invention relates to a method and to a liquid column damping system, in particular for damping vibrations, preferably structural vibrations, comprising a tank filled with a liquid, in which at least three preferably vertical columns of the tank, which are spaced apart from one another, in particular for forming communicating liquid columns, are connected by a base region of the tank that is common to all columns, wherein the tank is rotatably mounted about a vertical axis, in particular on a platform that can be rotated about the vertical axis, and, in directions perpendicular to the vertical axis of rotation, has natural frequencies f1, f2, f3, f4 that differ as a function of the direction, wherein the tank can be tuned in terms of the natural frequency f1, f2, f3, f4 thereof acting for a predetermined direction by rotation about the axis of rotation.

Abstract: The invention relates to a liquid column damping system, particularly for damping building vibrations, comprising a tank (B, S1, S2) filled with a liquid, said tank having, in particular, a substantially U-shaped geometry in at least one direction. At least two columns (S1, S2) of the tank arranged at a distance from each other, particularly for forming communicating liquid columns, are connected by a base region (B) of the tank, and means for adjusting the damping of the liquid column damping system and/or the natural frequency of the liquid column damping system are provided. At least one column wall region (W1) in at least one of the columns (S1, S2), preferably in all columns, can be moved in order to change the column cross-section.
