As Taiwan was pounded by gale force winds from Typhoon Soudelor on Saturday, the Taipei 101 stood strong.
But according to reports, the 508-metre skyscraper's tuned massive wind damper recorded its biggest movements ever as it helped offset the effects of 162 kilometres per hour winds.
Suspended between the 92nd and 87th floors, the 660-tonne sphere acts like a giant pendulum, counterbalancing against movements from severe weather and earthquakes.
On Saturday, the device reportedly swayed back and forth 100 centimetres.
The tuned mass damper helps maintain the balance between flexibility and rigidity needed to protect the structural integrity of the building, while also ensuring of comfort of its occupants and its glass exterior.
The Taipei 101 was ranked as the tallest building in world from its opening in 2004, but was trumped by the opening of the Burj Khalifa's in 2010 in Dubai.
Typhoon Soudelor hit southeast China late Saturday, after causing more than 101 injuries in Taiwan and knocking out power for more than 3 million households.
