STRUCTURAL INFO IN BRIEF

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 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 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

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.

8. Outrigger columns are
visible below the tower
’waist’ and perimeter
moment frame columns are
visible above.
Note a setback above each 8-
story module, the tower
’waist’ and double-notched
corners for wind load
reduction.
