The Examination Area cantilevers and is
suspended by large beams on the roof.
Columns in this area do not go to the
concrete slab below. Floor plates have
Vierendeel girders which carry the load.
East-end Structural System

Auditoria side of the building. Concrete sheet is
meant to curve and span 25 meters, yet maintain
a 20 cm thickness. This truss system helps to sup-
port the concrete.
West-end Structural System
Section through auditorium |
Within the space of the auditorium, OMA
wanted to maintain the 20 cm thickness
of the concrete. The span of the ceiling
however, was problematic.
Upper & lower pressure zones are
established within the concrete. Lower
pressure zones are in tension.
The longer the span, the thicker
the concrete needs to be & the
need for steel reinforcement arises.
Concrete in tension serves
no structural purpose. Thus,
OMA resolved to remove this
unnecessary zone. This main-
tains the strength, span, and
desired material thickness.

The columns in the cafeteria area decrease in quantity
as you move towards the North. It appears that there
are only two columns supporting the floor above at
this end. However, the two columns create a hybrid
truss with the slanted floor plane. The lower end of the
truss is within the floor slab.
Deformation of the space is created by this changing
density of columns.
Throughout the building, the Northern end is treated
openly while the Southern end is treated in a more
closed manner. This is expressed through materials
as well and levels of opacity and translucence.

- Maintaining the integrity of the concrete sheet
- Keeping the 20 cm thickness
- Concrete must remain continuous
- Has a constructive high point in the auditorium
- Regular in form
- Examination/testing block is more rigorous
- Typical steel frame with prefab. flooring
- Concrete sheet works as a connector between this
side and the West side to bring the two separate
- Maintaining openness
- Use of materials to express this openness
- Use of less obvious structure to express openness
- A more closed off environment
- Use of materials to express this
- Use of more structural columns to close space more
