The structural system of the building is cross-walled with a narrow (3,0; 3,3; 4,8 m) pitch of transverse walls and one longitudinal wall. External walls - 320 mm thick aerated concrete curtain panels with D600 characteristics; B2,5; F25 with additional insulation with rigid mineral wool boards 60 mm thick and plaster. The outer walls of the technical underground are prefabricated three-layer reinforced concrete panels 240 mm thick with expanded polystyrene insulation and additional insulation with aerated concrete and expanded polystyrene using galvanized overhead parts. Internal walls: technical underground - reinforced concrete panels 180 mm thick with openings for laying communications, standard floors - prefabricated reinforced concrete panels 160 mm thick. Interfloor floors - prefabricated reinforced concrete flooring 160 mm thick. The material of prefabricated reinforced concrete products is concrete of class B15÷B22,5, reinforcement of class AIII. The horizontal joint of the internal panels is platform, the vertical joint is with concrete dowels. The spatial rigidity of the building is ensured by the joint work of all elements, united by welded joints and concrete dowels. The static calculation of the load-bearing structures of the building, taking into account the joint work of the building with the base, was performed using the SCAD software package. The main load-bearing structures of the building are designed to meet fire resistance requirements in accordance with STO 36554501-006-2006. On the Lira 9.2 software package, a structural system was calculated for progressive destruction. The extension was designed according to the frame structural scheme. The frame columns are designed according to a grid of 3,3 - 3,0 m x 4,0 m. The frame elements are made of rolled steel profiles. Ceiling and covering are designed from monolithic reinforced concrete class B25, F100 with a thickness of 160 mm on steel beams. External walls are self-supporting, at the level of the technical underground - from concrete wall blocks, at the level of the first floor - from aerated concrete and brick with insulation and plaster. Spatial rigidity and stability of the extension is ensured by the joint work of vertical elements, rigid fastening of columns on supports and hard disks of floors and roofs. The foundations of a residential building are on a natural foundation, in the form of monolithic reinforced concrete slabs 600 mm thick. Concrete B25, W6, F150. The foundation of the extension is a monolithic reinforced concrete slab 300 mm thick. Under the foundations, a device for concrete preparation with a thickness of 50-100 mm is provided along a leveling layer of sand of medium size with a thickness of 50-70 mm. In accordance with the report on engineering and geological surveys, the basis of the foundations of a residential building is the EGE-2 soil - silty brown sands with interlayers of sandy loam, dense, saturated with water, with characteristics E \u180d 2 kg / cm30, φ \u0,65d XNUMXº, e \uXNUMXd XNUMX.

The project provides for the installation of an open-type staircase made of prefabricated reinforced concrete steps and a ramp made of monolithic reinforced concrete along steel stringers on a slab foundation. The spatial rigidity and stability of the car park is ensured by the hard disk of the pavement, rigid junctions of the columns with the pavement and their pinching into the foundations. The foundations of the parking lot are taken on a natural basis, strip, from monolithic reinforced concrete of class B25, F100, W8, in the form of cross strips with a footing width of 1200 mm. A 100 mm thick concrete preparation is provided under the foundation. In accordance with the report on engineering and geological surveys, the base of the foundation of the parking lot is silty brown sands with interlayers of sandy loam, dense, saturated with water, with characteristics E = 180 kg/cm2, φ = 30º, e = 0,65. The design soil resistance of the base is 1,46 kg/cm2, the average pressure on the base is 0,9 kg/cm2. The expected draft does not exceed 1,0 cm, the relative difference of the draft does not exceed the maximum allowable values. The calculation of the car park structures together with the base was carried out using the SCAD 11.3 software package. The relative elevation of 0,000 corresponds to the absolute elevation of 20.88 m. The construction of a parking lot and an extension is envisaged after the construction of a high-rise residential building. The block complete transformer substation (2BKTP) consists of two complete blocks of factory production of Ezois-North-West LLC.
