Structural and space-planning solutions.

The level of responsibility of buildings is normal. The constructive scheme is frameless. Spatial rigidity and stability are ensured by the joint work of load-bearing longitudinal and transverse internal walls, hard disks of floors and roofing. Calculation for stability, strength, spatial immutability of buildings as a whole, as well as individual structural prefabricated elements with attachment points, incl. to protect the building from progressive collapse, was made using the Lira-Sapr software package. Foundations - a monolithic reinforced concrete slab with a thickness of 400 mm from concrete of class B30, grade W6 for preparation with a thickness of 100 mm from concrete of class B10. The relative elevation of the bottom of the foundations is "- 2,900 m". The foundations are based on loams (IGE-2,4) with a minimum design resistance of 45,0 t/m2. The maximum pressure under the sole of the foundation slab is 11,5 t/m2. Maximum draft - 3,9 cm. Waterproofing - from two layers of "Technoelast" grade EPP according to TU 5774-003-00287852-99. Structural elements of the section are taken from prefabricated reinforced concrete products according to the 90 series, produced at the city's reinforced concrete plant. The roof is flat, with an internal organized drain, from two layers of "Technoelast" according to TU 5763-005-72746455-2007. The slope is provided with expanded clay gravel with a thickness of 20 mm to 100 mm (y=500 kg/m3).
