As Typhoon Bavi lashed Shanghai with powerful winds, the 1,000-tonne tuned mass damper (TMD), a device mounted in structures to reduce mechanical vibrations, inside the 632-meter Shanghai Tower swung into action. The damper moved by as much as two meters, absorbing the building's sway. Designed to withstand strong winds and earthquakes, the TMD offers a fascinating glimpse into the engineering systems that protect one of the world's tallest buildings. Boasting an impressive 128 floors above ground and five levels below ground, the Shanghai Tower is the tallest skyscraper in China and the third tallest building in the world. ๐บ Subscribe to our YouTube channel and stay updated with our latest analysis and interviews:๐ https://www.youtube.com/channel/UCgrNz-aDmcr2uuto8_DL2jg ๐ Download our APP on Apple Store (iOS): https://itunes.apple.com/us/app/cctvnews-app/id922456579?l=zh&ls=1&mt=8 Download our APP on Google Play (Android): https://play.google.com/store/apps/details?id=com.imib.cctv For more: https://www.cgtn.com/video Most watched videos: Impossible Challenge: 30 seconds to count banknotes BLINDFOLDED https://www.youtube.com/watch?v=ZmP_Ybj-jws Impossible Challenge: Gymnastics Boy Arat Hosseini from Iran! https://www.youtube.com/watch?v=8sxX--U4c8w Impossible Challenge: How to calm babies in 5 seconds? https://www.youtube.com/watch?v=kR3q9sXM7WA
