Structural and space-planning solutions.

The building of the sports and recreation complex. Building responsibility level – II (normal). The building of the complex is designed in three blocks - the central four-storey block and one-storey (gym and swimming pool). Blocks are designed in various constructive schemes. The structural scheme of the gym and swimming pool blocks is a one-story frame with a coating of curved glued wooden beams, hinged on reinforced concrete and steel columns. Beams of curvilinear shape, 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 ensured by vertical connections between steel columns, horizontal wooden and steel connections in the plane of the coating. The structural scheme of the central part is a spatial frame of monolithic reinforced concrete structures, rigidly interconnected - columns, floor slabs, walls - longitudinal, transverse and stairwells. Grid of columns - 6,0x6,0 m. Columns with a section of 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, pivotally resting on columns and located at different elevations. Beam span 18,0 m; removal of consoles 3,15 m; section of beams -220x1350 (h) mm. Glued wooden structures are treated with antiseptic bioprotective compounds. A profiled flooring with a polymer coating is attached to the wooden supporting structures of the coating. External walls of the complex: hinged steel three-layer "sandwich" - panels 150 mm thick; facade cassettes and stained-glass windows are attached to steel half-timbered structures. Partitions - aerated concrete 200 mm thick from aerated concrete blocks D 600, B 2,5, F50, brick 120 mm thick from hollow bricks and plasterboard on a steel frame. 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 250mm. 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 were completed, a positive conclusion was received for the project of wooden glued structures. Kucherenko. The foundations are monolithic reinforced concrete columnar and strip foundations on a natural foundation. Foundation concrete B25, W8, F100. Under the foundations and a monolithic reinforced concrete floor slab 200 mm thick, concrete preparation 100 mm thick is provided along a sand cushion 200 and 1200 mm thick. The calculation of the foundation is made according to the formulas of SNiP 2.02.01-83*. The relative elevation of 0.00 corresponds to the absolute elevation of + 5.120 m. In accordance with the report on engineering and geological surveys, the foundations are based on sandy plastic sandy loam with the characteristics of E = 130 kg / cm 2, φ = 25o and dusty hard sandy loam with E = 220 kgf / cm2, φ=24о. The design resistance of the foundation soils R = 7,3 kg / cm 2, the pressure on the foundation soil is not more than 3,3 kg / cm 2. The maximum groundwater level is at a depth of 0,4 - 0,6 m from the earth's surface. Groundwater is moderately aggressive in relation to concrete of normal permeability. In order to protect the concrete of underground structures, the concrete grade for water resistance is W8, 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 draft of the building is not more than ~ 3,1 cm. The modular boiler house is designed from easily assembled metal structures with "sandwich" paneling. Metal structures are made of a closed bent profile 140x100x6, etc. (connections from a bent profile 80x4) in accordance with GOST 30245-2003. The outer walls are hinged steel "sandwich" panels 100mm thick. The coating is made of "sandwich" panels 100 mm thick on a metal frame. Spatial rigidity and stability of buildings is provided by vertical connections and rigid junctions of columns and crossbars. The foundations are 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 mastic until full saturation. Chimneys (gas flues) with a height of 9 m and an outer diameter of 450 and 550 mm are fixed on a spatial metal structure installed on its own foundation. The metal structures of the exhaust tower of the chimneys are designed from racks (a pipe with a diameter of 89x5), united by a lattice of 70x6 corners. The foundations for the exhaust tower are columnar on a natural base. Concrete B20,W6, F50. The relative elevation of 0.00 corresponds to the absolute elevation of + 3,55 0m. In accordance with the report on engineering and geological surveys, the base of the foundations is a sand cushion 1,4 m thick, at the base of the sand cushion there are solid sandy loam with E=220kg/cm2, φ=24o.
