Structural and space-planning solutions

The level of responsibility of the building of the complex is II. The building of the complex is designed in the form of three blocks - the central five-story block and one-story blocks (gym and swimming pool). Blocks are designed in various constructive schemes. The construction scheme of the gym and swimming pool is a one-storey frame covered with bent-laminated wooden beams hinged on reinforced concrete and steel columns. Curvilinear beams, one- and two-span, beam spacing from 5,0 to 7,0 m. Beam span 21,0 m and 21,0 + 4,0 m. Beam width - 220 mm, height - from 832 to 1660 mm. Steel columns - from electric-welded pipes with a diameter of 325 mm with a monolithic reinforced concrete core. Spatial rigidity of the frame is provided by vertical connections between steel columns, horizontal wooden and steel connections in the plane of the coating. The structural scheme of the central block is a spatial frame of monolithic reinforced concrete structures, rigidly interconnected columns, floor slabs, walls (longitudinal, transverse) and stairwells. Grid of columns - 6,0 x 6,0 m. Columns - section 400x400 mm; 600x400 mm. Ceilings - beamless slabs 240 mm thick supported on columns through hidden cantilevers from channels. Walls - 250 thick; 300 mm. The material of monolithic structures is concrete of class B25, F100, W6, class AIII reinforcement. The block cover has a complex curvilinear shape. The load-bearing structures of the coating are single-span bent-laminated wooden beams with cantilevers, hinged on columns and located at various elevations. Span of beams - 18,0 m; removal of consoles - 3,15 m; section of beams -220x1350 (h) mm. Glued wooden structures will be treated with antiseptic bioprotective compounds. A profiled flooring with a polymer coating is attached to the wooden load-bearing structures of the coating. External walls of the complex: sandwich panels; facade cassettes and stained-glass windows are attached to steel half-timbered structures. The pool bowl with dimensions of 25x16 m is designed in monolithic reinforced concrete (B30; W8; F75). Wall thickness - 300 mm. The bottom of the pool is a beamless slab 300 mm thick, supported by columns with a section of 400x400 mm. Waterproofing from polymeric materials is carried out according to the technology of a specialized organization. Stairs are designed from monolithic reinforced concrete, B25 concrete. The elevator shafts are designed from monolithic reinforced concrete. Wall thickness 250 mm. Concrete B25, reinforcement AIII. The spatial rigidity and stability of the building is ensured by the joint work of the longitudinal and transverse load-bearing walls, the walls of the stairwells, the rigidity of the supporting nodes of the columns and the hard disks of the floors. The calculation of load-bearing structures was carried out on a computer using the SCAD Office program (version 11.1). Calculation and design documentation of wooden glued structures have been completed, a conclusion has been received for the project of wooden glued structures. The foundations are assumed to be piled. Piles - driven with a section of 350x350 mm, 9 and 11 m long. Concrete piles B25,W6, F100. Efforts in piles no more than 60t. Grillages - columnar and tape made of monolithic reinforced concrete, concrete class B25, W6, F75. Column grillages - 800 mm high and strip grillages - 600 mm high, united by a 200 mm thick plate. Pairing of piles and grillage is rigid. Under the grillages and the floor slab, a concrete preparation 100 mm thick is provided along a sand cushion 300 and 1200 mm thick. The relative elevation of 0.000 corresponds to the absolute elevation of +11.170 m. According to the report on engineering and geological surveys of IGL GeoProject LLC (reg. No. 0921/1) of 2010, the base of the piles are dusty gray dense sands with e = 0,55, E = 240 kg/cm2. The allowable design load on the pile is 60 tons, based on the results of static sounding. Before mass piling, the bearing capacity will be checked by static tests. After the installation of the pile field, control tests of the piles will be carried out. In order to protect the concrete of underground structures, the concrete grade for water resistance is W6, the concrete surface is protected by coating with a primer twice. The project provides for the internal waterproofing of the basement by applying Aquafin cement-polymer mastic to the surface. The expected average settlement of the building is not more than ~2,0 cm. Boiler room: The modular boiler room is designed from easily assembled metal structures with sandwich panel cladding. Metal structures are designed from a closed bent profile 140x100x6, etc. (connections from a bent profile 80x4) in accordance with GOST 30245-2003. External walls - hinged "sandwich" panels 100 mm thick. Covering - from "sandwich" panels 100 mm thick on a metal frame. The spatial rigidity and stability of the building is ensured by vertical connections and rigid junctions of columns and crossbars. The foundation is taken in the form of a monolithic reinforced concrete slab 250 mm thick, concrete B20, W6, F50. Under the foundation, crushed stone preparation 100 mm thick is provided with pouring with bitumen until full saturation. Chimneys (gas ducts) with a height of 9 m and an outer diameter of 450 and 550 mm are fixed on the spatial metal structure of the exhaust tower, installed on its own foundation. The metal structures of the exhaust tower of the chimneys are made of racks (a pipe with a diameter of 89x5) united by a grid of 70x6 corners. The foundations for the exhaust tower are columnar on a natural foundation. Concrete B20,W6, F50. The relative elevation of 0.00 corresponds to the absolute elevation of +9,57 m. According to the report on engineering and geological surveys of IGL GeoProject LLC (reg. No. 0921/1) of 2010, silty plastic sandy loams with Е=104 kg/cm2, φ=24о serve as foundation foundations. The design resistance of the base soil is not lower than R = 1.8 kg/cm2, the pressure on the base soil is not more than 0,19 kg/cm2. In order to protect the concrete of underground structures, the concrete grade for water resistance is W6, the concrete surface is protected by coating with mastic twice. The expected average settlement of the building is less than the maximum allowable.
