Abstract
A damping device for a tower-like structure, includes a liquid column tube having an arbitrary shape and a pair of opposite upstanding end portions thereof where liquid levels are formed, and an orifice provided at an intermediate portion within the liquid column tube, the liquid column tube being mounted upon the tower-like structure. The damping property of the damping device can be quantitatively defined by employing the orifice. Furthermore, as the intermediate portion of the liquid column tube defined between the opposite upstanding end portions can be appropriately configured, the installation space for the damping device is optimized.
