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 a swimming pool, sports halls, an aerobics hall and a gym, technical and utility rooms. The complex is designed for visiting 200 people per day. The main entrance to the building is provided from Danube Avenue. The building consists of three main parts and has a symmetrical composition. The central part of the building is designed as a 5-storey building with a complex curved roof. External walls at the level of 4-5 floors are designed with a reverse slope of 10%. The maximum height from the planning mark of the ground 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. The height of the three-light volumes from the planning mark of the earth to the highest point is 14,24 m. The roof is pitched along the general radius. The entrance vestibule is designed at elevations of -1,500 and 0,000 with a second light. Open staircases are designed in the lobby, connecting it with the basement floor. In the basement at around -3,300 are designed: a wardrobe, sanitary facilities, utility rooms, storerooms, technical rooms of the pool, a ventilation chamber and a heating center. On the ground floor at the 0,000 mark, a swimming pool with a 25,2x16 m bowl with bypass paths, a gym, inventory rooms, dressing rooms with showers, bathrooms and Turkish steam rooms, a medical office, administrative premises, a loading bar and utility rooms are designed. On the second floor, at elevation +3,300, two bars, VIP dressing rooms, sanitary facilities and utility rooms are designed. On the third floor, at elevation +6,600, the premises of the administration of the complex, meeting rooms, server room, control room, sound control rooms, sanitary units and ventilation chambers are designed. On the fourth floor, at elevation +9,900, an aerobics hall, a gym, dressing rooms with showers and sanitary facilities, a staff room and utility rooms are designed. On the fifth floor at +13,650, a sports hall, a ventilation chamber and an open gallery are designed. For vertical communication between floors, an elevator with a carrying capacity of 630 kg with cabin dimensions of 1100x1400 and two staircases of the L1 type is provided. External walls - three-layer "sandwich" panels and stained glass windows. Socle - reinforced concrete, lined with polished ceramic granite. Glazed canopies on metal brackets are designed above the main entrance. The roof is rolled with an organized drain. Partitions - made of reinforced concrete, aerated concrete, 100 mm thick post-ridge slabs, frame-sheathed with plasterboard slabs. In technical rooms and rooms with a wet regime - solid brick, 120 mm thick, plastered on both sides. The project documentation ensures the accessibility of the complex for people with limited mobility.

Structural and space-planning solutions

The level of responsibility of the building is normal. The building was designed according to the combined structural scheme. The material of the load-bearing structures is monolithic reinforced concrete, concrete class B25, F75, W6, steel structures, glued wooden covering structures. The columns of the frame of the central part are designed as monolithic reinforced concrete on a grid of 6,0x6,0 m with a section of 400x400 and 400x600 mm. The columns of the sports hall and the pool are made of metal from pipes according to GOST 10704-91, steel C245. The basement walls are external - monolithic reinforced concrete 300 mm thick, internal - monolithic 200 and 250 mm thick. The internal load-bearing walls of the building - the walls of staircases and diaphragms - are monolithic reinforced concrete with a thickness of 250 mm. External walls - non-bearing three-layer sandwich panels 150 mm thick. The panels are fastened with self-tapping screws to the fachwerk frame from a closed profile according to GOST 30245-2003, steel C245. Fachwerk fastening to - concrete with expansion bolts of the HILTY type. Ceilings and covering of the central part - monolithic reinforced concrete slabs 240 mm thick. Beams covering the halls - wooden glued. The span of the beams is 18,0-21,0 m, the spacing of the beams is 6,0 m. The rigidity of the coating disk is ensured by fastening the profiled sheet to the beams and partially horizontal ties. The spatial rigidity and stability of the building is ensured by the joint work of transverse and longitudinal load-bearing walls, transverse and longitudinal stiffening diaphragms, vertical braces, rigid fastening of columns on supports, and hard disks of floors and roofs. The structures of the stairs are monolithic reinforced concrete. Elevator shafts - monolithic reinforced concrete 250 mm thick. The calculation of load-bearing structures and the foundation was performed using the SCAD11.3 software package, taking into account the joint work of the building with the foundation. The maximum horizontal movement of the top of the building does not exceed 5 mm. Calculation and design documentation of wooden glued structures were completed, a positive conclusion was received for the project of wooden glued structures. Kucherenko. The required fire resistance of reinforced concrete load-bearing structures is confirmed by calculations. The foundations are taken on a natural basis, columnar, with a thickness of the slab part of 700 mm. Concrete W6, F100. The average pressure on the base is 3,5 kg/cm2. A 100 mm thick concrete preparation is provided under the foundation. The relative mark of 0,000 corresponds to the absolute mark of 13,880. In accordance with the report on engineering and geological surveys, the base of the foundation is the IGE-2 semi-solid loam soil with φ=22o, c=0,28, e=0,667kg/cm2, E=120kg/cm2. The design soil resistance of the base is 4,3 kg/cm2. In order to protect the concrete of underground structures, the concrete grade for water resistance is W8, the concrete surface is protected by a penetrating cement-polymer waterproofing. The expected draft of the building is 5,6 cm. There is no surrounding development at a distance of 30 m. The service life of load-bearing structures is 150 years.
