Abstract
A damping assembly for reducing wind-induced vibrations in elongated strures comprises a plurality of damping tubes suspended within the structure in end-to-end relationship so that the end portions of the damping tubes are disposed in abutting relationship with the inner surface of the structure. Each damping tube includes an elongated shell, vibration damping material such as sand filling the shell, and plug elements sealing the end portions of the shell. Rod elements are secured to the plugs to interconnect the damping tubes. In an alternative arrangement spacer elements are connected to the rods so that the damping tubes are supported at their end portions in an aligned relationship.
