Stabilization ball skyscraper Taipei in action
This amazing video was made May 12, 2008 in the highest skyscraper in Taiwan Taipei 101. On that day, a terrible earthquake happened in Sichuan province, in which 60 thousand. People were killed and 20 thousand. Missing considered. The ball, which you will see in the video, the biggest amartizator resonant mass (translated as I could 'tuned mass damper'). At the time of the earthquake there were people in the building. When it began to sway, a Rhuaalvin managed to shoot shock absorber in operation. It's amazing when you think that the ball weighs 728 tons, it is located on the 87 floor of the building height of half kilometer.
