Tall buildings often have tuned mass dampers hidden inside their structures to stabilize them against the wind. Those tuned mass dampers are huge and heavy and help limit a building’s movement by swaying in the opposite direction of the building. That is, if the wind is making a skyscraper sway to the right, the damper will sway to the left to dissipate the kinetic energy, and reduce the, um, swaying. What’s interesting is that the Burj Khalifa, the world’s tallest building, doesn’t have that.
Shun Hung Square is a 1,260-foot tall skyscraper that’s the third tallest building in Shenzhen, China. It’s really, really tall. And watching the guys from On the Roofs climb it gets more and more stressful because they just keep going up. You think they’ve reached the top but there’s still another level that’s narrower and more dangerous and higher to climb.
