Constructive decisions

The level of responsibility of the building is normal. Structural scheme - frame. The spatial rigidity and stability of the building is ensured by the joint work of columns, hard disks of floors and coatings, and stiffening cores, which are staircases. Calculation for stability, strength, spatial immutability of the building as a whole, as well as its individual structural elements with attachment points, incl. to protect the building from progressive collapse was carried out using the SCAD Office software package. Foundations - monolithic reinforced concrete columnar (under columns) with sole dimensions * 1200x1200 mm, 1500x1500 mm, 1800x1800 mm, 2100x2100 mm, 2400x2400 mm, 2700x2700 mm. 3000x3000 mm 3300x3300 mm and monolithic reinforced concrete tape (under the walls) 3600 mm wide from concrete class B3600, grade W4200 for preparation from concrete of class B4200 with a thickness of 5100 mm. Foundation laying depth - "-6,800 m" from el. 0,000. For the relative mark of 0,000, the level of the finished floor of the second floor was taken, which corresponds to the absolute mark of 176,30 m. The base of the foundation is a bedding of medium-sized sand with soil compaction until the volumetric weight of the soil skeleton is 1,65 t/m3 at optimum moisture content and a compaction factor of 0,95. The minimum design resistance of the base soil is 20,0 t/m, the maximum pressure under the base of the foundation is 19,12 t/m2. The maximum foundation settlement is 5,6 cm. Waterproofing - from bitumen-polymer material "TECHNOELAST P". Columns - monolithic reinforced concrete with a section of 400x400 mm from concrete class B30.

Vertical ties and spacers from rolling angles according to GOST 8509-9z - 80x6 mm, cross ties 75x5 mm from steel according to GOST 380-71 *. Runs - from channel No. 22 according to GOST 8240-89 from steel S245 GOST 27772-88 for spans of 5000 mm and 6000 mm and from paired channels No. 22 for spans of 7600 mm and 87001 mm.

External wall insulation - PENOPLEX 35 polystyrene foam boards (I> 031 W / mx ° C, y \u35d 5767 kg / m ') according to TU 006-56925804-2007-120 with a thickness of XNUMX mm. The walls of the first floor and the above-ground part of the basement wall (basement) are finished with porcelain stoneware slabs in accordance with GOST 6787-2001. All monolithic reinforced concrete structures above el. 0,000 are made of concrete. The outer walls of the first and second floors are non-bearing, made of cellular concrete blocks 0=0 25 W/mx°С v=500 kg/m3) according to GOST 31360-2007, 250 mm thick on a cement-sand mortar; the outer layer is a hinged facade system, the supporting basis of which is a frame made of galvanized steel profiles attached to monolithic ceilings and walls lined with ceramic-granite slabs; insulation between the layers - mineral wool boards "Venti Butts" (/.=0,041 W/mx°C, y=90 kg/m3) according to TU 5762-00d-457e20l-99.
