LIQUID COLUMN DAMPING SYSTEM

摘要

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.

1. A liquid-column damping system for damping building vibrations, the system comprising
a substantially U-shaped tank filled with a liquid and having at least two upright columns spaced horizontally from each other and a base region forming a fluid flow connection between the columns, at least one of the columns having a wall defining a horizontal cross section of the one column; to a body of liquid filling the base region and at least partially filling the columns; and means for adjusting the damping of the liquid-column damping system and/or the natural frequency of the liquid-column damping system by horizontally moving the wall to change the cross-section of the respective column.
