Taipei 101 Tuned Mass Damper

Damping System (Taipei 101)

Formerly called the Taipei World Financial Centre, Taipei 101 was the tallest building in the world in 2004 and remained as such until the construction of the Burj Kalifa in Dubai in 2009. Another notable distinction of Taipei 101 was that it was also LEED platinum certified making it the world’s tallest green building.

Construction of the 101 story skyscraper commenced in 1999 and concluded in 2004. It has served as one of Taiwan’s most famous landmarks ever since. The 101 floors represented optimism and a new ideal. With 100 being a number that symbolized perfect, 101 was a symbol of going beyond.

Today the building houses a number of professional offices, two restaurants, retail stores, a private club, an observation deck that is popular with tourists and is also a site for the city’s New Year’s Eve fireworks displays.

Given the tower’s location on the globe, special measures had to be taken to ensure it could withstand earthquake tremors and typhoon winds – both of which are quite common in Taiwan. Structural engineers designed the building to be flexible so that it could withstand gusts of wind up to 60m per second as well as earthquakes.  

Tuned Mass Damper Fabrication

Working with Motioneering Inc., A&H fabricated the cradle, connecting components, including the bumper and bumper brackets for the largest TMD (tuned mass damper) system in the world (a 730-ton suspended steel sphere), and the only one that is an architectural feature of a building. The TMD helps the building to withstand high winds and up to 40% of the building’s movements are reduced.

A&H also built and tested the pinnacle TMDs for Taipei 101. Altogether, the fabrication of components took just under one year to complete.

A&H has also built TMDs for the Trump World Tower and Bloomberg Financial Building in New York City.
