Structural and space-planning solutions

The control room and shed buildings are designed in a steel frame. Level of responsibility – II. The constructive scheme of the control room building is a complete frame. The node supporting the roof beams on the columns is hinged. The spatial immutability of the frame of the control room is ensured by the joint work of the columns, rigidly fixed in the foundation, and the hard disk of the cover. The rigidity of the coating disc is ensured by fastening the corrugated board to the girders in each wave on the extreme spans and through the wave on the middle spans. The sections of the main load-bearing structures of the frame were adopted: columns - square pipes according to GOST 30245-2003 from steel C255; roof beams - I-beam according to STO ASCHM 20-93 from steel C245, roof decking - H75-750-0.8 according to GOST 24045-94. As external enclosing walls, hinged wall panels of the “Sandwich” type 150 mm thick are used, the coating is corrugated board, laid directly on the upper belts of the coating beams. A fachwerk system has been developed for fixing wall panels. The foundation for the control room building is a non-buried monolithic reinforced concrete slab 150 mm thick, with monolithic beams along the contour and under columns 550 mm high, made of B20, W4, F50 class concrete. To prevent freezing of the base of the foundation slab, insulation with foam slabs is provided. A cushion of coarse-grained sand is arranged under the foundation slab. In accordance with the report on engineering and geological surveys, the base is the EGE-1 layer (plastic silty sandy loam), which has the following characteristics: ρн=2.04 t/m3; e=0.612; n =24о; Сn= 0.14 kg/cm2; E=100 kg/cm2. The average pressure under the sole of the foundation slab is 0.19 kg/cm2. The design soil resistance of the base is 2.53 kg/cm2. The expected settlement of the foundation slab is 0.3 cm. The spatial invariability of the canopy frame is ensured by the joint work of the columns, rigidly fixed to the foundation, and the hard disk of the profiled flooring, which is fastened with self-tapping screws in each wave. The node for supporting the main beams of the roof on the columns is hinged. Columns - I-beams according to STO ASChM 20-93 from steel C245, canopy beams are designed from I-beams according to STO ASChM 20-93 from steel C245, corrugated board - H75-750-0.8 according to GOST 24045-94. The foundations for the canopy columns are monolithic reinforced concrete columnar foundations made of concrete of class B20, W6, F150. In accordance with the report on engineering and geological surveys, the base is the EGE-1 layer (plastic silty sandy loam), which has the following characteristics: ρн= 2.04 t/m3; e=0.612; n =24о; Сn=0.14 kg/cm2; E=100 kg/cm2. The average pressure under the base of the foundation is 1.05 kg/cm2, the design soil resistance of the base is 2.82 kg/cm2. Expected draft - 1.7 cm, horizontal movement - 7.25 mm. The foundations of underground reservoirs are taken on a natural basis in the form of a monolithic reinforced concrete slab 400 mm thick, concrete class B20, W6, F50. The basis for the foundations for the tanks is the EGE-2 layer (silty sandy loamy fluid), which has the following characteristics: ρн=1.99 t/m3; e=0.700; n=19о; Сn=0.10 kg/cm2; E=70 kg/cm2. The design of the foundations provides stability against ascent. The project provides for coating waterproofing of the outer faces of the foundations in contact with the ground.  The calculation of the main load-bearing structures was performed using the SCAD software package version R11.3. The displacements and deflections obtained as a result of the spatial calculation of the building frame do not exceed the maximum allowable values. The relative mark of 0,000 corresponds to the absolute mark of 15.80. The groundwater level during the survey period was revealed at a depth of 1.6 - 1.8 m from the earth's surface at absolute levels of 13.46 - 13.02. The maximum level of groundwater is expected during periods of snowmelt and heavy rainfall is expected at a depth of 0.5 m from the day surface, at absolute levels of 14.28 - 14.61.
