of transferring the 17,000 seat South
Stand over the sliding pitch below. The
culmination of elegant architectural design,
robust structural engineering and careful
fabrication, the trees are the main feature of
the South Stand.
Beneath the South Stand there is a
series of mega transfer trusses, spanning
in three sections across the sliding pitch.
These trusses have been coordinated and
integrated with the architecture such that
the concourses, toilets, concessions and
vomitories are all as uninterrupted as
possible.
The connection design of these trusses
was complex, due to the size of the loads
and the location of the some of the splices.
“Minimising site durations was key
in the design and fabrication. Where
possible, bolted connections were used,
even in heavily loaded areas. In visible
areas, hand holes and recessed cover plates
allowed internal bolted connections to be
used, reducing the need for site welding
and shortening site durations,” says Mr
Shrubshall.
The loads in some of the structure are
significant and connection design was
incredibly complex. The combination of
heavy sections and high loads meant that
splice connections had to be carefully
located.
“Additional constraints such as the
distance between the sliding pitch surface
and the splice connections meant that even
the orientation of the bolts was considered,”
adds Mr Shrubshall.
The North Stand cantilevers 10m over
the tier below. This is formed using box
section rakers. The load is delivered into
the reinforced concrete cores, using prestressed
high strength bars. Significant
dynamic analysis has been carried out to
justify the performance of the stand. There
are significant service penetrations with the
North Stand, which allow the distribution
of services around the space below.
Meanwhile, the West Stand is supported
on a series of slender steel box sections
columns, which are 21m-tall. These
columns create a spectacular atrium space
below. There are also several propped
cantilever balconies and escalator
platforms, which are hung from the
structure above.
The judges say, the new stadium is not
just for football but provides a multifunction
entertainment facility. The
complex new building was constructed
on the confined urban site of Spurs’ old
stadium thus providing continuity for fans
and community.
The steelwork, which has been
finished to a very high standard, plays an
integral part in the form and architectural
expression of the new building.
