 Structural and space-planning solutions

 Residential sections are designed according to the cross-wall structural scheme of monolithic reinforced concrete and are separated by expansion joints. The spatial rigidity of the building is ensured by the joint work of transverse and longitudinal walls and piers in combination with unchanging horizontal disks of reinforced concrete floors and roofing. Bearing walls at the level of the basement and first floor - 300 mm thick - 160 mm, piers - 300 mm thick made of B30 concrete; W6 (for the basement); F75. Bearing walls in the level from the level of the second floor and above - 200 mm - 160 mm thick, piers - 200 mm thick made of B30 concrete (up to the level of the 10th floor); B25 (from the 11th floor and above); F75. Ceilings and roofing - monolithic reinforced concrete slabs with a thickness of 200 mm with thermal breaks in the area where the balconies are located from monolithic reinforced concrete B30 (floor over the basement and first floor) and B25; F100. The outer walls of the basement are made of monolithic reinforced concrete 200 mm thick with an outer layer of insulation and, above ground level, lined with SKC wall stone. External non-bearing walls of residential sections - from a layer of ceramic hollow brick M125 with a thickness of 250 mm, a layer of insulation with wall stone cladding (at the level of the 1st and 2nd floors) or a hinged facade system with an air gap "ALFORM" (TC No. 3434-11 ). The project provides for the fastening of non-load-bearing walls to the load-bearing structures of the building. Sections of external load-bearing walls - monolithic reinforced concrete 200 mm thick with an outer layer of insulation and subsequent cladding. Stairs - prefabricated reinforced concrete marching platforms. Elevator shafts - from monolithic reinforced concrete. Ventilation blocks - prefabricated reinforced concrete with floor-by-floor support on ceilings. The structures of entrances, porches and ramps are made of monolithic reinforced concrete on a natural base, separated from the structures of the foundations of residential blocks by an expansion joint. The building of the attached parking lot was designed according to the frame structural scheme of monolithic reinforced concrete; separated from the residential section by an expansion joint. The spatial rigidity of the car park building is ensured by the rigid connection of the columns with the foundations, the presence of stiffening diaphragms formed by the walls of the stair-lift assembly and the walls of the entrance ramps, and the horizontal disks of reinforced concrete floors and roofing. Columns - with a section of 500x600 mm. The walls of the stair-lift assembly and the walls of the entrance ramps are 200 mm thick with insulation and cladding of sections of the outer walls. The outer walls of the underground part of the car park are made of monolithic reinforced concrete 200 mm thick. The outer enclosing walls of the above-ground floors are in the form of a reinforced wall made of SKZ stone 130 mm thick with fastening to steel fachwerk elements. The outer enclosing walls of the above-ground floors in the area of ​​technical and service premises are made of aerated concrete blocks and a layer of insulation with cladding with SKC wall stone. Ceilings and roofing - monolithic reinforced concrete slabs 200 mm thick with capitals in the areas of support on columns 3000x3000x400 (h) mm and contour beams with a section of 600x400 (h) mm; entrance ramps and coating of the stair-lift assembly and ventilation chamber - 200 mm thick. The columns and walls of the car park at the level of the basement and 1-3 floors are designed from B40 concrete; F100; ceilings, roofing, columns and walls of the 4th floor and above - from B30 concrete; F100. Internal staircase - prefabricated reinforced concrete steps on metal stringers, based on monolithic reinforced concrete platforms. The external staircase is made of steel structures. The base of the floor of the first floor and the underground floor is a monolithic reinforced concrete slab 100 mm thick made of B22.5 concrete over a layer of polyethylene film, a layer of crushed stone 150 mm thick and a sand cushion with layer-by-layer hardening. The foundations of the residential sections and the parking lot are based on piles. Piles - bored reinforced concrete, carried out according to the "Fundex" technology; pile diameter 450/560 mm; working length of piles 28,05 m; absolute offset of the tip of the piles - minus 21,00 m; concrete B30; W6; F75. Grills of residential sections - from monolithic reinforced concrete in the form of cross tapes and slabs 1200 mm high. Parking lot grillages - free-standing piles 900 mm high under bushes, untied by foundation beams with a section of 900x900 mm. Concrete grillages - B25; W6; F100. Pairing of piles and grillage is rigid. Concrete preparation 100 mm thick is provided under the grillages.  Estimated load on piles is 200 tf. At the base of the tip of the piles of residential sections there is heavy silty solid loam EGE-10 with design characteristics: E=30 MPa; e=0,590, IL=-0,22. The design load on the piles was adopted based on the results of static sounding. Prior to the start of the mass installation of piles, design solutions provide for testing of piles. In order to protect the concrete of the underground structures of the residential sections and the parking lot from groundwater, the concrete grade for water resistance is W6, waterstops are provided in the concreting joints and drainage near the foundation is provided. The relative elevation of 0,000 for the residential part of the building corresponds to the absolute elevation of 11.35. The relative mark of 0,000 for the car park corresponds to the absolute mark of 11.10. The level of responsibility of buildings is normal. The calculation of the structures of residential sections and the parking lot was carried out using the SCAD 11.3 software package, taking into account the joint work of the building with the base.
