Taiwan’s towering landmark, Taipei 101, emerged unscathed from the recent 7.4-magnitude earthquake that struck the island, thanks to its innovative design featuring a colossal pendulum. This pendulum, affectionately known as ‘Damper Baby,’ played a crucial role in minimizing damage by absorbing the seismic shock.
Constructed from 41 layers of steel, the 660-metric-tonne pendulum hangs suspended between the 87th and 92nd floors, over 1,000 feet above the ground. Measuring nearly 18 feet in diameter, it swings within a limit of 59 inches, strategically engineered to counteract the building’s movement during earthquakes and strong winds.
The pendulum’s primary function is to reduce the building’s sway by up to 40 percent, offering stability and protection against seismic activity. Its pivotal role underscores Taipei 101’s resilience in the face of natural disasters, reaffirming its status as a symbol of architectural innovation and safety in earthquake-prone regions.
Furthermore, Taipei 101 boasts another remarkable feature: the Tuned Mass Damper (TMD), also known as the wind-damping ball. This passive system, tailored to the building’s specific needs, mitigates swaying caused by strong winds, enhancing comfort for occupants and visitors alike.
The TMD, a technical marvel in its own right, serves both functional and aesthetic purposes, drawing intrigued visitors eager to witness its operation firsthand. As the spherical damper oscillates back and forth during earthquakes or typhoons, it absorbs the force of intense swinging, further reducing the building’s movement by up to 40 percent.
Taipei 101’s success story serves as a testament to the effectiveness of innovative engineering solutions in safeguarding skyscrapers against natural disasters. As Taiwan’s tallest building and a global architectural icon, Taipei 101 continues to inspire awe and admiration while exemplifying resilience and adaptability in the face of adversity.
