The inner non-bearing elements such as an elevator shaft, staircase and service places have not been designed and
accepted as loading.
According to the project, the steel mast and reinforced concrete foundations are tightly connected placing one part into
other and stiffening with massive horizontal diaphragms that ensure the general behaviour of the construction.
The connection of reinforced concrete tubular structure of the tower and the foundation slab has been modelled as rigid.
The model has presented the bottom slab propped against an elastic soil.
Soil properties have been accepted with reference to the performed research. Calculations used two different models for
an elastic foundation: for a static analysis, the elastic foundation properties were found according to the deformation
modulus of the ground, whereas for dynamic deformation actions, a stiffer base was developed applying the elastic modulus
of the ground.
