An Iconic Landmark where Chinese Cultural Motifs Meet Modern Design

Taipei 101 is a 508-meter, 101-story tower with a unique profile representing a blossoming flower that signifies financial richness and everlasting vitality. The building design also incorporates the number eight, which connotes prosperity in Chinese culture, and references traditional bamboo construction. It was the tallest building in the world from 2004 to 2010.

We provided structural design concept and preliminary designs to C.Y. Lee Architects, reviewed the final structural design by the local engineer-of-record and advised the project team during construction.

Highlights

  • Eight repeating pagoda-like modules each consist of eight levels with a narrower base and wider top.
  • Our engineers worked with the architect and wind engineer to refine the building’s exterior form to reduce the strain from wind forces – an important consideration in an area subject to typhoons.
  • The structural system used a braced-frame core with multiple outriggers to accommodate the multiple setbacks in the building’s shape.
  • Additional seismic safety measures include use of perimeter moment frames and special core connections.
  • A 730-ton tuned mass damper that hangs from the 92nd floor reduces building movement caused by strong winds and earthquakes and increases occupant comfort.
  • The project includes a five-story deep basement and a surrounding six-story retail structure that includes a long span skylight.
