Galerie Šantovka in Olomouc is a multifunctional complex
with 46,000 m
2
of areas comprising shops, banks,
restaurants, a car park with 1,000 spaces, cinemas, an
18-lane bowling leisure facility, warehouses, and service
and loading communications. The whole object has a
substantially irregular elongated shape graduating from
the edges to its centre. Individual parts grow from the
coherent basement and are further divided by the internal
circular gallery. The largest length reached by the object is
235 m. It is divided into 14 expansion units. The building
consists of two underground floors and three overground
floors. Two bridge constructions are connected to the
object and a third one has been projected. In order to
reduce the construction time as much as possible, the
object was designed as prefabricated in its greatest part.
Only the necessary parts were designed as monolithic.
On the 3rd overground floor, occupied by multiplexes and
a theatre, it was especially steel constructions that were
used, due to variability.
Description of the skeleton
The object is embedded on a monolithic base plate with
stilts. The monolithic outside walls are located around the
whole perimeter of the object, apart from at the locations
of drive-up ramps. The staircases are prefabricated. The
basic pillar raster is 8.1 m x 8.1 m, with the stilt raster
being twice this measurement. The support system of the
1st overground floor - car park - consists of a reinforced
concrete prefabricated skeleton. The reinforced concrete
monolithic cores and beams are mutually interconnected
by the semi-prefabricated panel-board with a minimum
thickness of 250 mm. The beams are designed as
standard with a load width of 8.1 m, to a span of 8.1 m. In
the places under the tram, the load width is 4.05 m. The
standard pillar size is 500/500 mm and a maximum of
700/700 mm. The reinforced concrete cores and walls are
250 mm and 300 mm thick. The support system of the 3rd
overground floor - multifunctional premises, restaurants
- consists of a similar prefabricated system to that of the
lower sections, with added beams of the DELTA BEAM
construction system. In certain places, the floor slab is
necessarily finished with a reinforced concrete parapet.
Bowling and multiplexes - the support system consists of
steel pillars distributed around the perimeter and inside
the construction, on which the solid-web steel beams are
placed. The stability of the whole object is ensured by the
wall and ceiling fastening. The wall construction is made
of holorib. In the multiplex section, a steel ceiling grid
has been designed, on which the corrugated iron with a
concrete topping is placed.
Foundation and static load of the object
Prior to the object realisation, it was necessary to
construct a lagged building pit for the underground
floor development. The construction was built below
the groundwater level. The drilled stilts’ perimeter was
1,300 mm. The base plate, a maximum of 1,200 mm
thick, was designed to also withstand the buoyancy
of water up to the level of the inlet holes, because in
the case of the load of “1,000-year water”, the building
would be under threat. The considered load of the
multifunctional premises is from 6.5 kN/m
2
to 9 kN/m
2
.
Ramps for personal vehicles, trucks and sections under
the tram have the load set pursuant to the applicable
clauses of the ČSN EN 1991. In the places of intensive
greenery, the load on the plate is approx. 23 kN/m
2
. The
climatic load was considered. The seismic load was not
decisive in the design.
Description of the Calculation
From the project stage up to the production
documentation, the construction was drawn (projected)
in 3D, in the Allplan program from the Nemetschek
Company. From the drawing program, elements and
surfaces were exported through the ifc file in the Scia
Engineer program. Subsequently, the construction
was divided into expansion units. Individual units were
thereafter solved separately. Moreover, other smaller
sections were dealt with separately and then re-inserted
to the expansion unit. Basic verification in terms of
carrying capacity and deformation was evaluated in
the Scia program. The whole model contained 5,787
elements - 1D and 1,156 elements - 2D. A total of 49
load conditions were used, in basic and extraordinary
combinations. Production documentation of prefabricated
constructions was processed for 1,400 various types of
elements. The total volume of prefabricated elements was
approximately 13,000 m
