Reconstruction of some special types of constructions - silos, timber roof structure and a
winter stadium are described. The silos are cylindrical with a diameter of 36.0m with a total height of 50.5m. The silo shell is made from steel plates of variable thickness. Capacity of the silo is 60 000t. Gradually, during more than 30 years of operation, local deformations and distinctive 6000mm high cracks in the bottom part of the shells of the silos developed.
On the basis of diagnostic inspections and control static calculation a strengthening was
proposed. To increase working life of the clinker silos, the shell strengthening over the
whole height of the cylindrical body by means of horizontal rings and vertical stiffeners
was designed. The total S355 steel consumption for strengthening of one silo shell was 300t.
The original roof structure of a winter stadium in Zvolen was made of timber glued beams
with span of 55.5m. Some problems occurred during years of serving to its purpose.
Diagnostics showed that construction is unsatisfactory for the ultimate and serviceability
limit states. Deflection of the roof construction in the year 2005 was more than 500mm.
Authors proposed strengthening of the original beams (overall 34pcs) by prestressing.
The original reinforced concrete skeleton of Winter Stadium in Bratislava with plan
dimensions of 70.0 x 100.0 m was built in 1943-1952. During extensive modernisation of
Stadium, its steel roof structure is also prepared for basic reconstruction.
