Structural and space-planning solutions

The building is designed with a monolithic reinforced concrete spatial frame, consisting of columns, walls and beamless ceilings. The main grid of columns is 8,3x8,3 m. The junctions of the structures are rigid, designed to absorb bending moments. Spatial rigidity and stability is ensured by the joint work of vertical load-bearing elements with interfloor ceilings. Columns with a section from 600 x 600 mm to 1000 x 800 mm, depending on the load transferred to them. Internal walls 200 mm thick; 300 mm. Floor slabs - beamless 180 mm thick in the span and 320 mm in the inter-column sections in a mutually perpendicular direction. In the area of ​​the floor curling above the 2nd-6th floors there is a caisson slab 100 mm thick with ribs with a section of 200x800 mm, which rest on the capitals of columns 800 mm high with plan dimensions of 3200x3200 mm. On the 7th-8th floors, the bowls of the large and small pools are designed from monolithic reinforced concrete. The size of the large pool is 12x25 m, the small pool is curved. The bowls consist of a bottom 300 mm thick and walls of variable thickness 1,7 m high; 1,4 m and are supported by a system of beams 500 mm wide, 1450 mm high; 1750 mm. Construction material - class B25 concrete; B30;W6; F100, class A500C fittings. The covering of the main part of the building is designed from steel structures - a system of beams and purlins on which the profiled flooring rests. The stability of the coating structure is ensured by a system of horizontal ties and adjoining to the reinforced concrete structures of the building frame. On the roof of the building there are technical rooms (boiler rooms and ventilation chambers), designed with a steel frame and enclosing structures made of sandwich panels. Coating structures are designed taking into account technological loads and the weight of superstructure structures. The exhaust shafts and the 26 m high air duct on the roof of the building above the eighth floor are attached to the outer wall of the building. A two-level gallery is provided for connection with existing buildings. The structural scheme of the transitions is a steel frame with monolithic reinforced concrete ceilings along a profiled deck. The steel framing beams are cantilevered to the existing buildings and supported by the building's reinforced concrete columns and steel studs. The stability of the transition frame is ensured in the transverse direction by the frame connection of the uprights with stiffening crossbars, horizontal ties at the level of floors and roofing, and disks of flooring and roofing. External walls of the building: parking lot - hinged panels "Alumbond"; the rest of the floors - stained-glass glazing on steel fachwerk, fixed to the supporting structures of the building. Structural solutions for fastening the facade system to the supporting structures of the building are developed in the working documentation in accordance with the current technical certificate of the Ministry of Regional Development of the Russian Federation. The calculation of buildings was carried out using the SCAD 11.1 software package based on the spatial model of the building, taking into account joint work with the base. The level of responsibility of the building is normal. The main load-bearing structures of the building are designed to meet fire resistance requirements in accordance with STO 36554501-006-2006. The foundations were designed on the basis of engineering and geological surveys carried out at the construction site. Foundation design - monolithic reinforced concrete grillages on a pile foundation. Deep-laid grillages: under the columns - free-standing 1000 mm and 1500 mm high with a cluster arrangement of piles, under the walls - beams 1000 mm high, based on grillages. Grills and beams are connected by a 300 mm thick plate. Piles - bored with a diameter of 600 mm and a length of 36 to 42 m, depending on the height of the grillages, are made using the Atlas technology. Piles are made from the surface of the earth. Piling into grillages is tough. At the base of the piles at an absolute mark of minus 37,100 lie semi-solid dislocated clays with a total deformation modulus E=320 kg/cm². According to the results of static sounding, the calculated bearing capacity of piles, taking into account the reliability factor, is 494 tf. The design load on the pile is 300 tf. Static load tests of piles are provided. The project involves the construction of a deep underground volume: in the central part of the building - two underground floors (lower floor elevation minus 7,800); along the outer contour of the building - one underground floor (mark minus 5,400). For the construction of structures of the underground space in the central part of the building, a pit with a depth of 8,1 m is provided; along the contour of the building - a depth of 4,3 m. Waterproofing of the premises of the underground floors from groundwater: the use of concrete with the W8 water resistance mark for the grillage and external walls, the coating waterproofing of the closed contour of the underground space, the use of waterproofing gaskets in the working seams of concreting. The construction organization project provides for fencing the excavation with a sheet pile wall made of steel profile "Larsen IV" 18,0 m long. The calculation of the fencing was carried out taking into account the load from the existing building and technological loads on the edge of the excavation. To ensure the stability of the excavation fencing, temporary steel struts are provided for the period of construction of the basement of the building. The building is located in an existing building. Three buildings fall into the risk zone of new construction: multifunctional complexes "Zanevsky cascade -1"; "Zanevsky cascade -2" and a building under construction - an extension to the "Zanevsky cascade -1". Inspection of the technical condition of building structures has been completed. The buildings are built in monolithic reinforced concrete with pile foundations. The buildings are assigned to the 2nd and 3rd categories of the technical condition of structures according to TSN 50-302-2004. An assessment of the geotechnical situation at the construction site and the impact of construction on the surrounding buildings has been completed. The design settlement of the designed building is 6,8 cm. Additional settlements of existing buildings are 0,6 cm - 0,9 cm. For the entire period of work, the project provides for monitoring the condition of neighboring buildings with control of settlements, horizontal displacements, possible opening of cracks and the magnitude of dynamic effects. Zero cycle works are accompanied by observations of horizontal displacements of the excavation fence and changes in the position of the groundwater level in the adjacent territory. The relative elevation of 0,000 corresponds to the absolute elevation of 7,62 m.
