• Taipei 101 features a 508-meter, • 101-story tower• a five-story deep basement• six-story retail structure• most floor plan areas vary

between 2000 and 2500 square meters (21,500 to 27,000 square feet),

• though they are as small as 47 square meters above the main roof. Building aspect ratio (height/width) to the main roof is about 9 based on its ‘waist’ (and 6.8 counting the wider base).

•The Taipei 101 is built in the Hsinyi District of the city, the rapid-growing “Manhattan” of Taipei.

•The 508 m (1667’) Taipei 101 with a 101 story super-structure, a 5 story basement is a structural steel building.

• The total floor area, including a 6 story retail podium, adds up 370,000 m

The challenges to design and build a super-tall building in Taipei:

•height •natural constraints such as typhoon•Winds• frequent strong earthquakes •weak clayey soils

The structure is reinforced by a Moment Frame System linking the columns on all floors

36 columns provide vertical support, including eight mega columns around the perimeter.

The world’s largest passive tuned mass wind damper, suspended from level 92 down to level 88, helps to ensure stability and comfort.

The Tower is built on 380 concrete piles, sunk 80 meters into the ground

A damping system was implemented to reduce the excessive lateral accelerationsfrom wind

Tuned mass damper of stacked field-welded steel plates will swing as a pendulum on steel cables.

Outrigger columns are visible below the tower ’waist’ and perimeter moment frame columns are visible above.

Mall atrium roof is spanned by twin three-chord Vierendeel trusses.

Detail of atrium roof truss incorporates Chinese symbology.

Note a setback above each 8-story module, the tower ’waist’ and double-notched corners

for wind load reduction.
