Taipei 101 is a 101-story skyscraper located in Taipei, Taiwan. It features a 508-meter tall tower with a five-story basement and six-story retail structure. The tower has a steel superstructure supported by 380 concrete piles sunk 80 meters into the ground. It incorporates various damping systems like a tuned mass damper and outrigger columns to reduce movement from earthquakes and wind.

2. • 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).

3. •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

4. 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

5. The world’s largest passive tuned mass wind damper, 36 columns provide vertical support, including eight mega
suspended from level 92 down to level 88, helps to columns around the perimeter.
ensure stability and comfort.
The structure is reinforced by a Moment Frame System The Tower is built on 380 concrete piles, sunk 80 meters into
linking the columns on all floors the ground

6. A damping system
was implemented
to reduce the
excessive lateral
accelerations
from wind

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

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

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

11. Note a setback above each 8-story module,
the tower ’waist’ and double-notched corners
for wind load reduction.
