Structural and space-planning solutions

The control room and shed buildings are designed in a steel frame. Level of responsibility – II. 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 node supporting the roof beams on the columns is hinged. 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 C245; roof beams - I-beam according to STO ASCHM 20-93 from steel C245, roof decking - H57-750-0.8 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 top of the beam belt. 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 180 mm thick, with monolithic beams along the contour and under columns 650 mm high, made of B20, W4, F50 class concrete. Under the foundation slab, a complete selection of bulk soil is made, followed by the installation of an artificial foundation. To prevent freezing of the foundation slabs, insulation with Penoplex slabs is provided. The average pressure under the sole of the foundation slab is 1,94 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 operation of the columns, which have a rigid support unit on the foundation, with a hard disk of the profiled flooring, which is fastened with self-tapping screws in each wave. The main roof beams are pivotally supported by columns. The columns and beams of the canopy 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 B20, W4, F50. In accordance with the report on engineering and geological surveys, the base of the canopy foundation is the EGE-2 layer - heavy silty loam, hard-plastic, which has the following characteristics: e = 0,649; E=110 kg/cm2. The average pressure under the base of the foundation will be 1,05 kg/cm2, the design soil resistance of the base is 2,45 kg/cm2. The expected settlement is 1,7 cm. The foundations of underground tanks are taken on a natural basis in the form of a monolithic reinforced concrete slab 400 mm thick, concrete B20, W4, F50. The basis for the foundations for the tanks is the EGE-3 layer - light silty loam, semi-solid with gravel and pebbles, which has the following characteristics: ρн=2,16 t/m3; Сn=0,4 kg/cm2; e=0,471; E=140 kg/cm2. The design of the foundations provides stability against ascent. All foundations are laid on crushed stone preparation 100 mm thick, spilled with bitumen. 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 of the frames was carried out using the SCAD software package version R11.3. The maximum horizontal movement of the canopy frame is 13,67 mm. The displacements and deflections obtained as a result of the spatial calculation of the building frame do not exceed the allowable values. The relative mark of 0,000 corresponds to the absolute mark of 56.01. 9.2.4.
