General information.

The building of the educational institution is 4-storey. The overall overall dimensions of the building are 117,0 x 146,0 meters. The roof is flat. Under the entire building of the main academic building there is a technical underground. The height of the technical underground rooms is 2,08 m. The height of the rooms of 1-4 floors from the floor to the bottom of the floor slabs in most rooms is 3,6 m. Around The school building is designed with a driveway with a sidewalk 4,5 m wide. There are two entrances to the school territory. Maximum height from the driveway level to the 4th floor window sill is 15,0 m. The partitions are designed from non-combustible stone materials (brick, cellular concrete blocks, 100 mm thick plasterboard), which provides a fire resistance limit of more than EI 45. The width of the corridors is from 5,24 to 5,9 m. The dimensions of doorways in the light from the sports and assembly halls, to the staircases are 1,5 × 2,0 (h) meters. In the admin premisesnistration, classrooms, medical offices, the clear dimensions of doorways are at least 0,9 × 2,0 (h) meters. The distance from the premises located between the staircases to the emergency exit is no more than 20 meters. The structural design of the main building is frame-based. The spatial rigidity and stability of the building is ensured by the joint work of horizontal disks of monolithic reinforced concrete floors, monolithic columns, monolithic stiffening diaphragms, brick walls of staircases installed in two directions. Calculation of frame structures was carried out using the design and computing complex Structure CAD (SCAD). The structural design of the assembly hall is frame (metal frame). The stability of the assembly hall frame is ensured in the transverse direction by rigid fastening of the columns in the foundations, and in the longitudinal direction by ties. The spatial rigidity of the assembly hall building frame as a whole is ensured by a system of trusses, covering purlins and connections along them. Frame structures are designed to withstand vertical and horizontal loads acting on the building. Horizontal loads include wind loads, vertical loads include loads from the dead weight of structures, snow and temporary loads on floors. The level of the finished floor of the 0,000st floor is taken as the relative level of 1, which corresponds to the absolute level according to the general plan of 221,700. The foundations for the columns are designed as monolithic reinforced concrete. The columns of the main building with a cross-section of 400 x 400 mm are designed from monolithic reinforced concrete. For the columns, concrete class B25 F75 (GOST 26633-2015) is used, reinforced with A-III and A-I reinforcement in accordance with GOST 5781-82. The rigidity diaphragms are monolithic reinforced concrete, 200 mm thick. The diaphragms are made of class B25 F75 concrete (GOST 26633-2015), reinforced with A-III and A-I reinforcement in accordance with GOST 5781-82. The columns of the assembly hall are designed from closed bent-welded profiles with a section of 200×6 in accordance with GOST 30245-2003. The load-bearing structures of the covering are gable trusses made of closed bent-welded profiles in accordance with GOST 30245-2003 with a slope of the upper chord. At the ends of the building, the load-bearing structures of the covering are I-beams No. 25B2 in accordance with GOST R 57837-2017. The beams are supported by metal post-columns mounted on metal frame columns. Purlins are made from channels No. 24P in accordance with GOST 8240-97, vertical connections on metal trusses are made from square profiles 100×6,5 in accordance with GOST 30245-2003, horizontal connections on trusses from angle 80×7 in accordance with GOST 8509-93. The farm is made up of two shipping marks. Mounting connections are flanged. The truss is designed as a split free-supported structure. When calculating the truss elements, it was assumed that all the rods in the nodes are hingedly connected. The floor slabs of the main building are designed from monolithic reinforced concrete of class B25, F75. Plate thickness 220 mm. The floor slabs above the playroom, library, gymnasiums, and swimming pool are designed as monolithic reinforced concrete 220 mm thick along monolithic reinforced concrete beams with dimensions of 400x680 (h) mm and a pitch of 6,0 m. Reinforcement of the slab is provided by horizontal meshes of reinforcement with a diameter of 10 A-III, with a cell of 200 × 200 mm; if necessary, additional reinforcement is provided with individual rods with a diameter of 6, 8, 10, 12, 14, 16, 18, 22, 32 A-III. Reinforcement of beams is provided by frames made of reinforcement with a diameter of 12, 22, 32 A-III and 8 A-I. The covering slab above the transition to the assembly hall is designed from monolithic reinforced concrete of class B25, F75. Plate thickness 220 mm. The ceilings above the ventilation chambers and inventory in axes AA-YA/1, 27-35 are monolithic reinforced concrete on permanent formwork made of galvanized profiled sheets in accordance with GOST 24045-2016. The floors are supported by metal beams made of channels in accordance with GOST 8240-97 and I-beams in accordance with GOST R 57837-2017. The beams are plastered over a reinforcement frame made of ∅8A-I and mesh N20-1,6 GOST 5366 - 80 with a layer of at least 40 mm thickness. Fire resistance of structures is at least R45. Flights of stairs are made of prefabricated reinforced concrete steps GOST 8717-2016 on metal stringers. Stringers are made from channels in accordance with GOST 8240-97 and I-beams in accordance with GOST R 57837-2017. The landings of the stairs are monolithic reinforced concrete on permanent formwork made of galvanized profiled sheets.
