 Structural and space-planning solutions

 The constructive scheme of twenty-six-story one-section residential buildings is a cross-wall system with load-bearing internal transverse and longitudinal walls. Non-bearing external walls - from aerated concrete blocks D500, B2.5, F50, with floor-by-floor support on floor slabs, with external insulation (layer thickness 80 mm) and finishing with a suspended facade system with an air gap device.

Fastening the insulation to aerated concrete - dish-shaped dowels. The system of a suspended ventilated facade adopted in the design documentation with fastening of vertical load-bearing profiles to floor slabs through brackets will be calculated and developed at the stage of "working documentation" and will have a relevant valid technical certificate of the Ministry of Regional Development of the Russian Federation. Bearing external walls - from monolithic reinforced concrete 160 and 250 mm thick with insulation and finishing like non-bearing walls, on the ground floor - 180, 200, 250 mm thick. The outer walls of the basement are made of monolithic reinforced concrete 250 mm thick. Basement walls - with external insulation with a layer of extruded polystyrene foam 60 mm thick, above the blind area - finished with Melikonpolar concrete stone 120 mm thick. Concrete B30, W6, F100, class A500C reinforcement. Internal walls - from monolithic reinforced concrete 160 mm thick. Concrete B25 reinforcement class A500C. In the basement and on the first floor, the internal walls are 180 mm thick, part of the walls are replaced by pylons and columns. Columns - with a section of 400x400 mm, pylons - with a thickness of 250 and 400 mm. Concrete B30 reinforcement class A500C. Ceilings and coverings of residential buildings - continuous slabs of monolithic reinforced concrete 180 mm thick, with rigid support on the walls on three sides.

Elevator shafts - from prefabricated reinforced concrete volumetric blocks with a wall thickness of 120 mm. Concrete B25. Elements of stairs - prefabricated reinforced concrete marches and platforms made of monolithic reinforced concrete. Balconies and loggias of apartments - with stained-glass glazing made of aluminum profiles and a fence made of bricks 120 mm thick with steel fachwerk. Loggia stairs - with steel railings and brick railings. The spatial rigidity and stability of residential buildings is ensured by the box-shaped structure of the basement and the joint work of the bearing longitudinal and transverse walls with rigid disks of monolithic floors. The constructive scheme of two underground single-level parking lots is column-wall. Bearing structures of car parks - from monolithic reinforced concrete. Concrete B25, (exterior walls made of concrete B25, W6, F100), working reinforcement A500. Columns - with a section of 400x800 mm, with a maximum pitch of 8,0x6,9 m. External walls of car parks - 300 mm thick. The outer walls of the stairs above the blind area - 200 mm thick with insulation and finishing with a thin plaster layer with painting. Internal walls - 200 mm thick. The covering is a continuous slab 350 mm thick, in the column area - with capitals 600 mm thick (taking into account the thickness of the slab). The cover over the entrance ramp to the car park is a translucent structure made of a steel frame and polycarbonate cover. Elements of stairs - prefabricated reinforced concrete marches and platforms made of monolithic reinforced concrete. The spatial rigidity and stability of the underground car parks is ensured by the box-like structure and the joint work of the columns and outer walls, united by the cover disk. The structural scheme of the closed multi-level car park is frame-wall. The supporting structures of the car park are made of monolithic reinforced concrete. Concrete B25, working reinforcement A500. External non-bearing walls - from concrete wall blocks 190 mm thick with painting. The columns of the building are made of monolithic reinforced concrete with a section of 400x800 mm, with a maximum step of 7,9 x 6,8 m.

Ramps - slabs of monolithic reinforced concrete 250 mm thick on beams with a section of 300 x 500 (h) mm. Elements of stairs: marches - prefabricated reinforced concrete, platforms - from monolithic reinforced concrete. The spatial rigidity and stability of the multi-level car park is ensured by the rigid connection of all reinforced concrete elements of the skeleton and the joint work of the frame with the hard disks of the floors. Structural calculations were performed using the certified software package Monomakh and Lira in a finite element model, taking into account the joint work of the building, foundations and foundations and the mutual negative influence of neighboring buildings. The fire resistance of structures is ensured due to the installation of a normalized value of the protective layer of concrete up to the axis of the working reinforcement. The level of responsibility of residential buildings and parking lots is the second (normal). The service life of buildings is assumed to be at least 50 years. For residential buildings and parking lots, the mark of the finished floor of the first floor of residential buildings, corresponding to the absolute mark of 0,000, is taken as 28.50. The foundations were developed on the basis of engineering and geological surveys. The foundations of residential buildings and multi-level car parks are piled, the foundations of underground car parks are slabs on a natural foundation. Piles of residential buildings - prefabricated reinforced concrete, section 350x350 mm, length 12 m (from the bottom of the grillage 11,40 m long), driven from the bottom of the pilot pit by driving. Piles - from concrete B30, W6, F150 and fittings A400 and A240. The absolute mark of the bottom of the piles is 13.40. The connection of piles with grillage is rigid. Piles of a multi-storey car park - prefabricated reinforced concrete, section 350x350 mm, length 14 m (from the bottom of the grillage 13,45 m long), immersed by indentation. Piles - from concrete B30, W6, F150 and fittings A400 and A240. The absolute mark of the bottom of the piles is 13.00. The connection of piles with grillage is rigid. According to the results of static sounding, the calculated load on the piles of residential buildings is 121 tf, on the piles of a multi-level car park - 100 tf, and will be verified by static and dynamic tests. The base of the piles of residential buildings is silty plastic and solid sandy loam (IGE5 and IGE6), with e = 0,491, E = 12 MPa, φII = 23°, IL = - 0,32. The base of the piles of the multi-storey parking lot is silty plastic and hard sandy loam (IGE6), with e = 0,491, E = 12 MPa, φII = 23°, IL = - 0,32. Grills of residential buildings - slabs of monolithic reinforced concrete 800 mm thick. Concrete B30, W6, F100, working reinforcement A500C. The absolute mark of the bottom of grillages is 24.80. The grillages of a multi-storey car park are columnar piles under a bush with penetration into the ground below the freezing depth. The slab part of the grillages is 600 mm thick. Concrete B25, W6, F150, working reinforcement A500. The absolute mark of the bottom of grillages is 26.45. Multi-storey car park - without a basement, with the floors of the first floor on the ground. Floor slab - 200 mm thick. Foundations of underground car parks - slabs of monolithic reinforced concrete 600 mm thick. Concrete B25, W6, F100, working reinforcement A500. The absolute mark of the bottom of the foundations is 23.83. The maximum pressure in the base of the foundations is no more than 10 tf/m2. The base of the foundations of the car park of the first stage - silty plastic sands (IGE3), с e = 0,635, E = 9 MPa, φII = 22°, IL = 0,71 e = 4, E = 0,550 MPa, φII = 28°. The design resistance of soils at the base of the foundations of parking lots is not less than 68 tf/m2. Preparation under the grillages and foundations of buildings - a layer of monolithic concrete B7,5 with a thickness of 100 mm. The maximum groundwater level is at a depth of 0,0-0,3 m at an absolute mark of 26.70-28.60. Groundwater is moderately aggressive in terms of sulfate content in relation to concrete of normal permeability. Protection of residential buildings and underground car parks from groundwater and dampness: drainage, box-shaped basement structures made of W6 concrete, cold concreting joints - with hydraulic seals. The underground structures of the buildings are designed from concrete on sulfate-resistant Portland cement. In connection with the construction of residential buildings and underground parking lots in pits up to 3,3 m deep, in water-saturated soils, the design documentation provides for the installation of sheet piling of the excavation with Larsen IV sheet pile, 11,0 m long, immersed by indentation simultaneously for buildings I and II stages.
