Architectural and space-planning solutions

The project documentation for the site provides for the construction of an indoor sports complex without stands for spectators. The building is complex in plan with dimensions in the extreme axes of 68,00 x 45,03 m. The building is designed to accommodate a sports complex. It has been designed: a swimming pool, sports halls, an aerobics hall and a gym, technical and utility rooms. The main entrance to the building is provided from the Volkhonskoe highway. The building consists of three main volumes and has a symmetrical composition. The central part of the building is designed as a 5-storey building with a roof in the form of a complex curvilinear outline. External walls at the level of 4-5 floors are designed with a reverse slope of 10%. The maximum height from the planning ground level to the highest point of the roof is 22,85 m. Glazed staircases are designed along the longitudinal axis of the central part. On both sides of the central part, adjacent three-height volumes of a sports hall and a swimming pool with utility rooms are designed.

Structural and space-planning solutions

The building of the complex structurally consists of three blocks - a central five-story block with a basement and one-story blocks (gym and swimming pool). The level of responsibility of the building of the complex is II. 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 steel columns and reinforced concrete columns of the central block. Steel columns - from electric-welded pipes with a diameter of 325 mm with a monolithic reinforced concrete core. Coating beams - curvilinear outline with a section of 220x1660 (h) mm (in the span) and 220x832 (h) mm (on the support), one and two-span. The span of the beams is 21,0 m and 21,0 + 4,0 m, the spacing of the beams is from 5,0 m to 7,0 m Covering - corrugated board according to the system of main beams and secondary girders. Spatial rigidity of the frame is ensured by the rigid connection of the columns with the foundation, vertical connections between the steel columns and the hard disk of the cover. The rigidity of the coating disk is ensured by the presence of bracing blocks, including wooden spacers and cross metal braces made of round reinforcement. At the ends of the blocks, one-story shelves are designed in the form of monolithic reinforced concrete beam slabs 240 mm thick, based on internal reinforced concrete columns with a section of 40x40 cm and external steel columns. The structural scheme of the central block is a spatial frame made of monolithic reinforced concrete structures. The material of monolithic structures is concrete of class B25, F100, W6, reinforcement of class A500. The spatial rigidity of the central part of the building is ensured by the joint work of vertical elements - columns and longitudinal and transverse load-bearing walls, united by monolithic reinforced concrete floor disks. Columns - monolithic reinforced concrete with a section of 400x400 mm, 400x600 mm, a grid of columns - 6,0x6,0 m. Bearing walls - monolithic reinforced concrete 250mm thick. Ceilings - beamless slabs 240 mm thick supported on columns through hidden cantilevers from channels and, partially, slabs on monolithic reinforced concrete beams with a section of 400x600 (h) mm. The load-bearing structures of the coating are bent-glued wooden beams, curvilinear in shape, with a section of 220x1350 (h) mm and 220x1085 (h) mm, located at different elevations. Beam span 18.0m with cantilevers 3.15m. Covering - corrugated board according to the system of main beams and secondary girders. Stairs - monolithic reinforced concrete marching platforms 200 mm thick. External walls of the complex: "sandwich" - panels 150 mm thick, facade cassettes and stained-glass windows with fastening to steel half-timbered structures. The outer walls of the basement floor are monolithic reinforced concrete 300 mm thick with an outer layer of insulation. The pool bowl with dimensions of 25,2x16m is designed in monolithic reinforced concrete (B30, W8, F75). The thickness of the pool walls is 300 mm. The bottom of the pool is a beamless slab 300 mm thick, supported by columns with a section of 400 x 400 mm. Waterproofing - from polymeric materials, is carried out according to the technology of a specialized organization. The static calculation of the load-bearing structures of the complex was performed using the SCAD software package version 11.1. The calculation of the structures of the central block has been completed. Calculation and design documentation of wooden glued structures have been completed. The project of glued structures received positive conclusions. Foundations - on a natural basis, free-standing columnar (under the frame columns), strip (under load-bearing walls) and 700 mm thick slabs (under an elevator shaft) made of monolithic reinforced concrete B25, W6, F100 with class A500 reinforcement. Under the foundations, concrete preparation is provided with a thickness of 100 mm. At the base of the foundations - dusty sandy loam with nests of sand with gravel, pebbles, boulders, plastic and solid EGE 3 (e=0.382, φ=26 degrees, =2.21tf/m3, E=110kg/cm2) and EGE 3a (e=0.329 , φ=27deg., =2.26tf/m3, Е=160kg/cm2). The base of the floor of the sports hall is a monolithic reinforced concrete slab 200 mm thick for concrete preparation and a sand cushion with layer-by-layer compaction 1200 mm thick. Along the contour of the outer walls of the sports hall, retaining walls-beams made of monolithic reinforced concrete 300 mm thick were designed. The project provides for coating waterproofing of concrete surfaces of foundations in contact with the ground. The project provides for the treatment of glued wooden structures with antiseptic bioprotective compounds. The relative elevation of 0,000 corresponds to the absolute elevation of 16,90 m. Draft of the building - 5 cm. The project provides for the installation of a free-standing gas boiler. Building responsibility level – II. The boiler house building consists of two prefabricated containers, which are installed on a monolithic reinforced concrete slab 250 mm thick made of concrete B20, W6, F50. The container, 9,0 x 3,27 m in axes, is a steel frame made of rolled profiles with enclosing structures made of "sandwich" panels. A monolithic reinforced concrete plinth is provided along the perimeter of the slab. The depth of the foundation is higher than the depth of soil freezing. Under the foundation slab, a sand cushion with layer-by-layer compaction is provided. The projected chimney is a 8.4 m high truss-type supporting lattice tower with two gas exhaust shafts. The load-bearing tower is a spatial triangular vertical structure with dimensions of the faces in the plan of 1.2 m, consisting of steel pipes with a cross section х89х5 and crates of corners 70х6. Steel 255. An anti-corrosion coating is provided for the steel structures of the carrier tower. Gas exhaust shafts - pipes with a diameter of 400 mm and 350 mm made of stainless steel with thermal insulation. Gas exhaust shafts are attached to the supporting spatial structure with a step of 3,2 m. The chimney is designed as a cantilever with rigid fixation into the foundation by means of anchor bolts. The foundation of the chimney structure is a monolithic reinforced concrete detached with a plan size of 2.1х2.1m, height 1.7m made of concrete class B20, F50, W6. The base of the foundation of the chimney and the underlying layer of the sand cushion under the foundation plate of the boiler house are heavy silty loams with interlayers of sand with rare gravel, semi-solid EGE 2 (e=0.614, φ=24deg, c=0.36kg/cm2, E=125kg/cm2). The relative elevation of 0.00 corresponds to the absolute elevation of +15,33 m.
