VIDEO/ The 7.4 magnitude earthquake shook Taiwan, why the 101-story skyscraper
Taipei 101

Despite the 7.4 Richter earthquake that struck Taiwan early Wednesday, the Taipei 101 skyscraper in the center of the country's capital remained intact, just as its construction predicted.

The 509-meter-high building has a special structure inside it that reduces its shaking by 40% during earthquakes, but also on days with strong winds.

Watch in the video how the skyscraper behaved during the earthquake of April 3, 2024:

The structure is a steel ball weighing 660 tons located inside the building, on the 92nd floor, like a pendulum.

Whenever the building moves in one direction, the steel ball moves in the opposite direction and thus maintains the overall balance of the building, Daily Mail reports. In this way the skyscraper wobbles, but cannot fall.

In the video below you can see how the sphere behaved during the 6.8 Richter earthquake in 2022. This is a "passive damping system", which means that it works without any external force or control, only gravity and the movement of the building.

Meanwhile, hydraulic pistons under the massive sphere absorb and dissipate energy as heat.

As Dr Agathoklis Giaralis, a professor of structural dynamics at the City of London, explains to the Dail Mail, the steel ball of the "Taipei 101" works in a similar way to the way shock absorbers work in car suspensions.

Modern skyscrapers are built to be flexible, especially those in earthquake zones like Taiwan, Professor Anthony Darby of the University of Bath explains to the Daily Mail.

The materials from which they are made are elastic, that is, they stretch or contract according to the changing loads applied to them.
