1. The Emirates Stadium ARCH241
Alexander Venditti + Ankit Gongal

3. Why construct a new stadium?
Capitalize on greater match- day ticketing revenue
Increase capacity from 38,000 to 60,000+
Develop a world class stadium to match the club’s aspirations on the field
Previous ground, Highbury (constructed 1913) lacked modern faculties and overall spectator comfort Bring in off-season revenue

4. The essentials Architect – Populous ( formerly HOK Sport)
Structural Engineer – Buro Happold
Location – London
Construction start date – July 2003 (opened 23 July 2006)
Construction cost – £390 million
Capacity – 60,261

5. The Site 17 acre triangular site bounded by railway lines
Half a mile from the old stadium
Previously an industrial estate, so needed to buy out the land and finance relocation
Redevelopment of the surrounding area central to the project

6. The Shape Ellipse, rather than a more traditional rectangle
Allows compliance with noise level zoning
codes and minimize disruption
Designed to allow as much natural light as
possible
Dictated by the site
Construction depth kept to the minimum to
avoid disrupting the skyline

7. Stadium Superstructure
Combination of steel and concrete elements
Lower tiers supported by reinforced concrete rakers
Upper tier supported by the frame and the structural steel work

8. Roofing options – Post and Beam
Simplest and oldest
Row of columns parallel to the pitch
Rare in modern stadia
Obstructed views due to the
columns
“Goal post” structures

9. Roofing options – Cantilever
Fairly standard
Roof only supported from the back
Cellular beams often used to deal with uplift

10. Roofing options – Tension tied
Resist all loads through tension
Often created highly curved shapes
Cable net or structural membrane options
Lightweight and sophisticated

11. Roofing options – Space/rigid frame
Similar to post and beam but supports only
at the end
No restricted views
Used in the Emirates Stadium
System of 3 dimensional primary, secondary
and tertiary trusses

12. The Roof Structure Roof supported by combination of trusses
Triangular in section, made of
welded tubular steel
Two large trusses span 200m in
North-South direction
Hollow section members
Compression and tension girders
with struts resisting
out of plane
movement

14. The Roof Structure Fabricated on-site in two halves in tubular steel
Trusses are supported by the stadium's vertical concrete cores and are connected to
them by steel tripods
Series of 64 articulated props help transmit the loads from the perimeter to the rear of
the rakers
Prismatic perimeter ring truss – inherently stable against lateral torsional buckling

15. The Structural Organization

16. The Roof
Translucent polycarbonate dish-shaped roof suspended above the seating bowl
The underside is clad with metallic panels that provide a seamless appearance
Allows maximum sunlight
Diffused sunlight and eliminating harsh sun shade

19. The Roof Construction More expensive than tensile roofs
Allows for simultaneous structural steelwork and precast elements being constructed offsite
Significantly reduce construction time

21. The concrete cores Eight concrete cores within the elliptical
perimeter
Gives stability
Houses vertical circulation
routes and service
distribution routes

22. The concrete cores
Each concrete core houses four stairways, a passenger lift plus service access
Useful landmarks for spectators
All loads transmitted to the ground through a system of 600mm diameter bored cast in-
situ piles (extend 18m into the underlying London clay)

23. The model Steel wire, aluminums rod, plywood, clay, wood
Emphasis on the structure
1:600

24. What can we learn?
Emphasis on public transport, eliminating the need for huge car parking facilities
Not just a stadium, but a redevelopment of the surrounding area – urban regeneration
Completed ahead of schedule, and on budget
