Taipei 101 Mass Damper Recorded Its Second-biggest Movement By An Earthquake

During the magnitude 6.0 earthquake on August 8 in Taiwan, Taipei 101's tuned mass damper saw a 15cm movement when the quake hits at 05:28 in the morning which epicenter in southeast of Yilan. 

The movement of the damper was recorded as the second biggest movement by an earthquake.

It is also recorded as the fourth biggest movement of the damper overall. The 20cm movement of the damper by an earthquake in Taiwan happened also this year last April 18 when the 6.1 magnitude struck Hualien County.

The Taipei 101 damper has a diameter of 5.5 meters (18 feet) and a weight of 660 metric tons, it is the world's largest and heaviest wind damper that reduces up to 40 percent of the building's movement. The damper helps the tower to balance and reduces the swaying of the buildings due to heavy wind or earthquake.

Thought the recorded 100 centimeters movement due to strong winds brought by Typhoon Soudelor on August 8, 2015 tops the list the biggest movement in the building's history due to typhoon and its strong winds. 

While the second-biggest movement ever by a typhoon was registered on July 13, 2013, when it moved 70 centimeters as a result of Typhoon Soulik.

The Taipei 101 management now also a closer look at the movement of the tuned mass wind damper of the building since Typhoon Lekima will affect the northern part of Taiwan.
