the enormous steel ball you see in the photos (and the incredible video below) 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. if that makes no sense, watch the crude gif below.

Alex HalavaisTaipei 101 has a 768 ton damper on the 87-91 floors, and it is open and visible to visitors. The site has a video of visitors watching the oscillations being dampened during the Sichuan quake.
