2/51

When is a span a large span???

When, as a consequence of the size of

the span, technical considerations areplaced so high on the list of

architectural priorities that they

significantly affect the aesthetictreatment of the building.

The primary steel structure of the Stadium

includes 24 curved double columns spaced

regularly around the building perimeter.

Secondary and tertiary curved

structural elements overlay

the primary structural grid.


36/51

Each column was fabricated on the ground and set

in place, with nodes ready to receive other

members of the superstructure.

The concrete interior structure of BeijingNational Stadium was in place before

work began on the steel exterior

Horizontal trusses intersect at manylocations as they span from the perimeter

columns to the central ring

Stairways wind through the exterior

structural frame ofBeijing National

Stadium.

The complex overlapping steel structure,

though largely open, creates apsychological buffer between inside and

out.

Unusual light fixtures hang within the

steel framework of Beijing National

Stadium.

A translucent shading system is affixed to the

underside of the stadium's structure.

Each steel column location bears an equal share

of the superstructure's weight, which totals 45,000

metric tons

Beijing National Stadium seats

nearly 100,000 spectators.
