STRUCTURAL DESIGN

GRAVITY LOAD

Gravity loads are carried vertically by a variety of columns.

Within the core, sixteen columns are located at the crossing points

of four lines of bracing in each direction. The columns are box

sections constructed of steel plates, filled with concrete for addedstrength as well as stiffness at the 62nd floor and below.

On the perimeter, up to the 26th floor, each of the four building

faces has two super-columns, two sub-supercolumns, and two

corner columns. Above the 26th floor has the two super-columns continue

upward.

STRUCTURAL DESIGN

LATERAL LOAD

Lateral forces are resisted through a combination of braced

frames in the core, outriggers from core to perimeter

supercolumnsand moment resisting frames in the perimeter and

other selected locations.

Wind Dampers are used to reduce lateral vibrations due to wind.
