Workshop testing for Tuned Mass Dampers for the Greenland Centre Sydney residential tower was completed at TESolution structural lab in Korea last April. 180 ton moving mass is designed to slide back and forth on top of the Linear Motion Guides while most of its vertical load is dispersed throughout 4 rubber bearing columns that can freely move horizontally as shown on the above pictures.
The TMD is on its way to Sydney at the moment, and it will be installed on the top floor of the tower somewhere in this up coming summer.
The design of TMD utilizing rubber bearing column is very unique as it can be tuned to the structure with extremely low natural frequency while maintaining relative low vertical installation space as opposed to traditional pendulum type TMDs.
