Architectural and space-planning solutions

A de-icing materials warehouse building with an administrative and amenity building (ABC) was designed. The warehouse building with the administrative and administrative complex is complex in plan with dimensions in the extreme axes of 88,0x46,10 m. The maximum height from the planning mark of the ground to the ridge is 15,10 m. The main volume of the warehouse building is one-story. On the south side, a 3-storey building is designed. The height of the first floor is 3,6 m, the second - 3,83 m, the third - 3,2 m. In the warehouse building at a relative elevation of 0,000, storage of anti-icing materials and reagents in flights on 3-tier racks and related equipment for snow and ice removal is provided. At a relative elevation of +1,050, a ramp with a zone for the reception and departure of products, a room for a water metering unit and a heating point, and a sanitary unit are designed. In the building on the first floor, at a relative elevation of 0,000, the following are designed: a charging room, a storekeeper's room, an electrical panel room and an entrance vestibule. On the second floor, at a relative elevation of +5,250, there is a pantry that is not in good condition, a ventilation chamber. On the third floor, at a relative elevation of +9,450, there is a storage room, a director's office, a rest room, a negotiation room, two administrative premises, an inventory room, a wardrobe for staff, showers and a sanitary unit. Five evacuation exits are provided from the warehouse premises directly to the outside. The racks are designed with transverse passages 6,1 m high and 3,8 m wide. An emergency exit is provided from the building through a stairwell of L1 type. The building is designed as a frame type, columns and ceilings are made of monolithic reinforced concrete. Exterior walls - "sandwich"-panel element-by-element assembly. Plinth - brick to a height of 2 m Roofing - flat rolled on a profiled sheet with an external organized drain. Internal partitions - brick, frame-sheathed with a soundproof layer and made of aerated concrete blocks. Floor coverings and finishing of walls and ceilings are adopted in accordance with the purpose of the premises.

Structural and space-planning solutions:

The building was designed according to a frame structural scheme, divided by an expansion joint into 2 blocks along the length. Columns - from monolithic reinforced concrete, section 600 x 400 mm, main pitch 12 x 12 m, in the embedding 12 x 6 m. Concrete B30, working reinforcement A-500S. The ceiling is a monolithic reinforced concrete slab with a thickness of 120 and 200 mm on reinforced concrete beams. Beams with a section of 400x450mm400x1000mm. Concrete B25. Covering - steel trusses with a span of 12 m with a step of 12,0 m, made of closed bent-welded profiles (upper chord - from □ 140 x 120 x 6, lower chord - from □ 120 x 6, lattice - from □ 80 x 5) and beams I-beam profile No. 30B140B1 on which lattice runs from closed bent-welded profiles and profiled flooring H75 are laid. Horizontal stiffness ties at the level of the upper chord of trusses and vertical stiffness ties from the truss plane - from closed bent-welded profiles. Pipe steel C255. Vertical connections of the frame - cross - from closed bent-welded profiles. The outer walls of the building are sandwich panels of element-by-element assembly 110 mm thick, from the bottom to a height of 2 meters, brick walls 380 mm thick are made of ceramic bricks of the KORPO 1NF/100/2.0/25 brand. Partitions - from aerated concrete blocks 200 mm thick, brick 120 mm thick and from plasterboard sheets on a metal frame with filling min. cotton wool 125mm thick. The spatial rigidity and stability of the building is ensured by the joint work of the frame, vertical ties and the hard disk of the coating and ceilings. The load-bearing structures were calculated on a computer using the SCAD Office v.11.3 program and manually using the SNiP formulas. Stairs - prefabricated reinforced concrete steps on steel stringers. The foundations of the building are piled. Piles - prefabricated reinforced concrete, driven, section 35x35cm, length 12,0m. Pile driving is provided by the indentation method. Concrete B25, W6, F200. Pairing of piles and grillage is rigid. The allowable design load on the pile (39,3 tf) was adopted based on the results of static sounding (according to the calculation, the maximum force in piles is no more than 38,2 tf). Before mass pile driving, the bearing capacity of the piles will be checked by static tests. After driving the piles, control tests of the piles will be carried out. Grillages - columnar piles under the bush, made of monolithic reinforced concrete, 450 mm high. Concrete B25, W6, F200, working reinforcement A-500C. Preparation for grillages - from a layer of monolithic concrete B7,5, 100 mm thick over a layer of sand 200400 mm thick. The calculation of foundations was carried out by "SCAD Office" v.11.3. A relative elevation of 0,000 corresponds to an absolute elevation of +8,100 m. In accordance with the report on engineering and geological surveys, the base of the piles are light silty loams with gravel and pebbles with high plasticity with IL=0.47, E=105kg/cm2. The maximum groundwater level is near the daylight surface. Groundwater is slightly aggressive to concrete of normal permeability in terms of the content of aggressive carbon dioxide. In order to protect concrete of underground structures, concrete of reduced permeability W6 was used. The expected average settlement of the building is ~8,0 cm. There are no surrounding buildings within the 30-meter zone.
