How Does Taipei 101 Protect Itself from Earthquakes?
Taipei 101, one of the world's tallest buildings, stands as a landmark in a region known for seismic activity. Situated in one of the planet's most earthquake-prone areas, the architects and engineers of Taipei 101 recognized the importance of installing robust safety measures to protect the building and its occupants. This article delves into the unique earthquake protection mechanisms employed by the iconic skyscraper.
The Role of Base Isolators
Among the innovative features of Taipei 101, base isolators are a critical component in safeguarding the structure during seismic events. These advanced isolators allow the building to move independently of ground motion, effectively minimizing the impact of earthquakes on the structure. By design, base isolators work by reducing the amount of energy transferred from the ground to the building during an earthquake.
Tuned Mass Damper: An Advanced Safety Measure
In addition to base isolators, Taipei 101 is also equipped with a tuned mass damper, a large pendulum located near the top of the building. This structure is often referred to as the "tuned mass damper" due to its ability to stabilize the building and reduce resonance caused by swaying during seismic events and high winds.
The tuned mass damper is particularly important in the context of typhoons that frequently occur during Taiwan's typhoon season. The massive yellow globe, known by the playful nickname "Damper Baby," hangs suspended from eight steel cables between the 87th and 91st floors. During a earthquake, the pendulum absorbs the incoming force, deflecting it and significantly reducing sway. This not only preserves the structural integrity of the building but also ensures the safety of the occupants.
Monitoring and Maintenance
Building management takes great care in monitoring the functioning of the tuned mass damper. An almost surrealist camera is continuously filming the ball to provide real-time data on its movement. During a seismic event, the footage often captures the ball swinging back and forth while the building itself remains relatively still, demonstrating the effectiveness of the system.
