Structural Information
As can be seen in the single line diagram (Figure 1), the loads
will follow a large number of paths to the
foundations below. Snow, live, and dead loads are all
transferred through a complex web of steel and
reinforced concrete to the base. The cross bracing at the
interface between the roof structure and bowl, as
well as reinforcing steel in the bowl help to resist the lateral
load created by wind.
Figure 1 Single line diagram showing the load paths through the
building structure.

This web of steel is used to channel the
roof and snow loads to the outside of the bowl structure, in
accordance with the No obstructed view
requirement set by the client.

Figure 3 Aerial view of Wembley Stadium during steel roof
erection. With no columns to support the roof
inside the stadium, a complex web of steel was used to channel
loads out to the bowl edges.
Figure 4 This section shows the required sight lines set forth
by the Football Association, as well as the
slope of the roof structure.

Figure 6 Seen in this figure are the pile locations used in the
construction of Wembley Stadium. A number
of pile cap layouts were utilized for this project, from 2-piles
to 5-piles per pile cap. As can be seen at the
Eastern Arch Base there were 19 piles combined under one pile
cap to support the load from the 440 foot
high 1040 foot long arch.
Figure 7 This soils cross-section at the location of the Eastern
Arch Base shows the layout of the 19 piles in
the pile-cap. Also shown is the depth to which these piles were
required to reach in order to support the load
created by the arch.
Upon reaching the ground, the loads are dispersed into a series
of 4000+ piles which stretch up to 45 meters
(approx. 150 feet) into the earth (seen in Figures 6 & 7).
This is required in order to reach soil that is suitable
for supporting the overall loads of the stadium.
