Checking calculation for static analysis of Ice Arena on Khodynskoye Field (Northern Administrative District of Moscow)

The purpose of this work was to perform checking calculations of reinforced concrete structures in the Ice Arena on Khodynskoye Field for specified loads.

The performed calculations included:

  • calculations for loading of the structure with its proper weight;
  • calculations for loading of the structure with its proper weight + superimposed load (weight of people);
  • calculations for loading of the structure with its proper weight + superimposed load+ snow load;
  • calculations for loading of the structure with its proper weight + superimposed load+ snow load + yielding of foundation.

A finite element model of reinforced concrete framing from 0,000 level to 38,800 level was developed. The number of joints in the model 1,141,000, the number of elements =1,277,000.
The cover hingedly supported by embedded items of cover slab (level 38,800) was not modeled. Load from the cover was defined to the slab on 38,800 level.

Finite element model of the structure

The design model included a part of ramp adjacent to the building frame.
All vertical bearing elements of the reinforced concrete framing, including pillars, wells of elevator and stairway enclosures, and pylons were defined in the model by solid elements with nonlinear properties of concrete.

Finite element model of the structure (sectional view)

Reinforcement was defined by one-dimensional elements in the pillars and by two-dimensional elements in cast-in-place walls of elevator wells.
Horizontal bearing elements, including floor slabs, stand slabs and ramp slabs were defined by two-dimensional elements. Floor beams were defined by one-dimensional elements.
