in action: a skyscraper’s amazing 728-ton stabilising ball | deputydog
the enormous steel ball […] is the world’s largest ‘tuned mass damper’ and sits near the top of the world’s largest completed skyscraper on earth, taipei 101 in taiwan. the idea behind a tuned mass damper is quite simple: as a building sways (resulting from high winds, earthquakes etc), its tuned mass damper, essentially a finely tuned and ridiculously heavy pendulum, will move in opposition to the structure’s oscillations and minimise any movement.
