The project
The NOKIA Arena building complex –located directly above railway tracksT

he arena in the city of Tampere in
the south-west of Finland was designed by Daniel Libeskind. It serves
as a venue for ice hockey matches andconcerts and can accommodate up
to 15,000 spectators. A concrete slab
forms the foundations of the entire
complex, which consists of the arena,
a hotel and two adjoining residential
tower blocks. Four railway tunnels run
under the slab. Part of the hotel is located on top of the arena.

To protect the arena from the vibrations caused by trains passing underneath and to offer high-quality living
and working conditions in the hotel
and the towers, all the buildings had

The Getzner solution
to be acoustically decoupled from theconcrete slab. Part of the hotel is attached to the arena via pairs of pillars, which means it also needed to
be isolated from the arena.
This poses a particular challenge: theextremely high point loads of up to
7,000 kN exerted on the pillars. In addition, the climate in Tampere is veryharsh and it can be bitterly cold in thewinter. One of the reasons that a decision was taken early in the projectto opt for the decoupling expertiseand solutions offered by Getzner werethe company’s excellent references inbuilding isolation projects. After all,the elastic bearing has to function reliably for decades, as swapping it out
at a later date is not an option.

Point and strip bearings for extremeloads in confined spacesPoint loads of up to 7,000 kN, temperatures as low as -30 °C and top
performance over the long term: theHRB HS series from Getzner was the
only solution on the market capable ofmeeting these stringent requirements.
The highly resilient Sylodyn® bearings
provide the necessary mechanical rigidity and a good degree of elasticity.
Over an extended period they can reliably decouple structures subjected toloads as high as 12 N/mm2.
Customised solution for aspecial situation
The pillars of the building are completely decoupled from the concrete

Challenging vibration isolation design: the hotel
is attached to the arena using separate, decoupledpairs of pillars – as seen on the left of this photo.
The hotel rests on the left side of each pillar, thearena on the right.

The railway lines underneath the complex are verybusy. A prerequisite for ensuring that the complex
could be used as envisaged was the complete
decoupling of all parts of the building.

The ‘High Resilient Bearing’ (HRB) series fromGetzner takes up very little space yet provides loadtransmission figures of up to 12 N/mm² to provide
effective vibration protection.

Feedback
slab by point bearings, while thewalls are equipped with strip bearings. Stairwells and lift shafts penetrate the concrete slab right down to
track level. The differing levels overwhich the structures had to be decoupled demanded a lot of the Getzner
specialists during the planning of
the vibration isolation, explained
Andreas Wenz, a project engineer
at Getzner Werkstoffe: “The unusual foundation configuration of theNOKIA Arena complex posed numerous challenges for us when designing
the isolation solution. At some locations on the tower walls we had toprovide three separate bearing points
for multi-axis loading conditions.”
To compensate the tensile loading of
the pillars, customised bearing designs occasionally had to be planned.

While installing the bearings, prestressed elements were used to takeaccount of the enormous weight thatwould be placed on the pillars when
the structure is complete.
Decoupled as planned
The elastic bearings were installed by
the SRV Group. Two of the partners in
the project, Christian Berner andAkukon, oversaw the installation of
the critical decoupling components.
All the hard work paid off: measurements taken retrospectively confirmedthat the stringent requirements of theclient were fulfilled as expected.

What does the acoustic consultant
have to say about the project?
„The solution that Getzner provides
for the elastic shielding of buildings is
as unique as the construction project
itself. I’m proud that we were able to
make such a significant contribution
to this prestige project.“Tuomas Laitinen
Christian Berner

In its final configuration, thecomplex will have three furthertowers added – as shown on theleft of the diagram.
