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.
