Architectural and space-planning solutions

The design documentation provides for the construction of a multi-storey open-type car park building to accommodate cars for 298 cars. The building - 5 - storey, with a basement, with two staircases of type L1 and one staircase of the 3rd type. The outline of the building plan is taken in accordance with the shape of the site. The main dimensions of the building in the axes are 60,83x37,00 m, the height of the building from the surface of the adjacent territory to the top of the parapet is 17,42, to the top of the parapet of the staircase is 20,52. The building is frame, with monolithic columns and ceilings. External enclosing structures - metal lattice fencing anchored to load-bearing reinforced concrete structures and cantilevered steel shutters on the northeast, southeast and southwest facades. The coating is flat, the roof is with a top protective layer of concrete slabs. Gutters - outdoor, organized. The parking lot is not intended for storing vehicles with engines running on gaseous fuels (compressed and liquefied gas). To provide access for people with limited mobility to the parking building, ramps with a standard slope and standard dimensions of openings are provided. On the 1st floor, a security room with utility rooms, a room for primary fire extinguishing equipment and technical rooms are designed. There are 14 parking spaces in the basement, 1 parking spaces on the 36st floor (27 of them for people with limited mobility), two boxes for one parking space and one box for two parking spaces. On the other floors - 61 parking spaces. The exit of the cleaning equipment to the roof of the car park is designed along a ramp. Roof lighting is intended only for cleaning the roof at night. The car park has two entrances and two exits. Two double-track ramps are designed to move cars inside the building between the half-floors of the car park. The slope of the ramps does not exceed 18%, wheel fenders 0.1 m high are provided on both sides of the carriageway of the ramp, the middle barrier separating the carriageways has a width of 0.3 m. To ensure the movement of vehicles on the mezzanine, measures are provided to ensure safe movement: traffic light regulation on each mezzanine, road signs, horizontal and vertical markings, and viewing mirrors. The main façade is asymmetrical. Finishing of the main plane of the facade - colored plaster. The longitudinal load-bearing reinforced concrete wall is designed with openings with an area sufficient to ventilate the floors.

Structural and space-planning solutions

Building responsibility level – II. The design documentation provides for the construction of a 2-section frame car park building in monolithic reinforced concrete. All bearing elements are made of monolithic reinforced concrete class B25, F150, W6. A temperature expansion joint is provided between the sections of the building. The structural scheme of the building is column-wall with a longitudinal column spacing of 7,5 m and a transverse one of 5,5 and 7,5 m. Columns are accepted with a section of 400 x 800mm and 400 x 400mm. The outer walls of the basement are 400mm thick. Internal walls (stiffness diaphragms and stairwell walls) - 200mm thick. Ceilings, roofing and ramps - beamless slabs 250 mm thick, with contour beams with a section of 400 x 450 (H) mm. External enclosing structures of the building - a metal lattice fence with fastening to the supporting structures of the frame with stainless steel anchors. The external walls of the administrative and amenity part are self-supporting, made of solid brick M100, F50 250mm thick, with internal insulation with mineral wool boards 150mm thick. Fire wall - non-bearing, made of bricks M100, F 50 250 mm thick, with floor-by-floor support on floors. Stairs - prefabricated reinforced concrete marches on monolithic platforms. The evacuation ladder is a separate 400 mm thick foundation slab on a natural base, a spatial connection structure made of rolled steel channels and square pipes, fixed from horizontal movements to the ceilings of the building along the entire height. The spatial rigidity and stability of the building is ensured by the joint work of vertical elements united by monolithic floor disks. The load-bearing structures of the building were calculated using the SCAD11.3 PC. The relative elevation of 0.000 is taken as the absolute elevation of 5,250 m. The foundations are piled, with monolithic reinforced concrete free-standing and tape grillages 900 mm high. Under the grillage, a concrete preparation is made of class B10 concrete with a thickness of 100 mm. Piles - driven with a section of 350 x 350 mm, 14 and 15 m long. The connection of piles and grillage is rigid. Material of piles and grillage - concrete of class B25, W6, F150, reinforcement of class AIII, AI. In accordance with the report on engineering and geological surveys, the tip of the piles is immersed in dusty sandy loam with gravel and pebbles, with sand lenses, gray, hard (E=190 kg/cm2; e=0,306; IL=-0,26). The calculated pile load of 120 tf was adopted based on the results of the calculation and confirmed by pre-design tests of soils with driven piles with a static indentation load, performed. The expected settlement of foundations is 11÷ 15 mm, the difference in settlement is 3,8 mm. The design documentation provides for control tests of piles. Floor slab - from monolithic reinforced concrete 200 mm thick, on a sand cushion of medium-grained sand with layer-by-layer compaction. The project provides for the installation of a fire tank in monolithic structures made of concrete of class B25, F150, W6. The bottom is 300 mm thick, the walls and covering are 200 mm thick. Under the bottom, a concrete preparation is made of class B 7,5 concrete 100 mm thick, at the base there is a sand cushion of medium-grained sand 500 mm thick, underlain by bulk soils. The maximum position of groundwater - during the period of snowmelt and precipitation - at a depth of 0,5-1,0 m from the surface of the earth. Groundwater is non-aggressive towards concrete of normal permeability. The normative depth of soil freezing is 1,5 m.
