Architectural and space-planning solutions

The projected multifunctional complex (MFC) includes three buildings with different functional purposes, united by a single pedestrian zone. The construction of the complex is planned in three stages. The designed MFC building is the first stage of construction. The building is designed as a 3-storey building with an upper technical floor and a basement with attached underground facilities for unloading goods and a built-in-attached one-story underground parking lot. The MFC building provides for the placement of shopping areas (for rent) and entertainment areas designed on three floors in axes 1-29, I-F and A-I. At the moment, on the site allotted for construction, there are: the underground part of the previously unfinished building, subject to dismantling, and two separate transformer substations. The IFC building has two compositional axes, the first of them - from South to North and is a continuation of the channel (monument of architectural heritage), the second - from West to East perpendicular to the first. The main pedestrian zones are designed along the compositional axes. The main entrances to the building are designed from the corners of the building, in the southwest and northeast of the building. Additional entrances - along the compositional axis of the channel and divide the building along the axis of symmetry. The exits are oriented towards an open car park, along the highway, and a housing estate projected along the canal. Economic zones are projected from the western and eastern facades. The entrance ramps to the underground car park, cargo yard and loading areas are designed from the side of the highway. In the underground floor (multi-level basement) a hypermarket, a parking lot at 417 cars and technical rooms are designed. The first floor of the MFC building is entirely provided for rental trade in manufactured goods. In addition to the rental premises on the first floor, a cargo yard (loading) serving all floors of the MFC, service premises with a medical station, two service entrances with security and a cafe for visitors were designed. On the second floor, leased premises for the sale of manufactured goods are designed. On the third floor, a cinema complex with 7 cinema halls, a food court, a restaurant, commercial rental premises, premises of the management company and technical premises with ventilation chambers are designed. The technical floor is reserved for ventilation chambers, a cold attic and film projection rooms. The height of floors from the first to the third is 5,4 m. The height of the underground floor (basement) is variable. In the area of ​​the trading floor of the hypermarket, auxiliary and auxiliary premises of the hypermarket, the cargo yard of the hypermarket, the height is 6,5 m. In the area of ​​the car park, ramps and technical rooms, the height is 4.0 m. In the area of ​​the attached underground car park and the ramp serving it, the height, taking into account the structure, is 3.25 m. from the floor to the bottom of the structure 2.8 m. The central pedestrian passage of the first floor has multi-light spaces that combine it with the second and third floors into a single volume, in which vertical communications for buyers are designed. Placement of pre-air intake chambers is provided between the transformer substations and the designed MFC building. The decoration of the cinema complex provides for the use of fireproof and slow-burning materials: fiberglass, mineral plates, fiberglass, plasterboard sheets, etc. The basement of the building according to the design documentation is faced with natural polished light gray granite. Exterior walls made of sandwich panels filled with ROCKWOOL mineral wool. The wall panels are provided for hanging the Kraspan VA facade system with cladding with Kraspan-AL composite panels. The façade is finished with planar glazing, which plays a decorative role. Stained glass windows - from single-chamber double-glazed windows The entire structure of the roof of the multifunctional complex is carried out on metal trusses and beams. Two types of roof construction were used, the first is a folded metal roof over a galvanized metal profile crate, ventilated. On metal galvanized corrugated board. The second type of roofing is isoplast. Roof covering in axes 3-10 and in axes 20-27 of isoplast in 2 layers. The plots are divided in half by a protective layer of sidewalk concrete slabs. In axes 10-20, the roof is metal. Skylights are designed on the roof. For communication between floors in the MFC building, 13 evacuation stairwells of the H2 type, 6 passenger-and-freight elevators Q=1600kg, 2 passenger elevators Q=1600kg, escalators and travolators were designed. The height of the MFK body from the day surface to the roof level is 27.00m The project documentation provides for measures to ensure access for the disabled.

Structural and space-planning solutions

The level of responsibility of the building is normal. The designed building consists of a multi-storey part, attached underground facilities for unloading goods and a built-in-attached one-story underground parking lot. The building is divided by two temperature-sedimentary seams along the length and one temperature-sedimentary seam along the width. The attached parts of the one-story underground car park and underground goods unloading facilities are separated by a sedimentary seam from the main part of the building. The building was designed according to the frame-braced design scheme. The frame columns are prefabricated reinforced concrete of individual manufacture from B45 concrete, with a section of 600 x 600 mm, the main grid of the columns is 16,2 x 8,1 m. Crossbars - prefabricated reinforced concrete tee sections of individual manufacture from concrete B45, with a section height of 890 (h) mm. The walls of the stairwells and stiffening diaphragms are monolithic reinforced concrete 200 mm thick made of B30 concrete. The outer walls of the basement are monolithic reinforced concrete 400 and 600 mm thick. Concrete B30, W8, F150. External enclosing structures - in the form of stained glass windows. Structural solutions for fastening stained glass 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. Floor slabs - prefabricated reinforced concrete multi-hollow prestressed, bench formless molding 15,6 m long, 500 mm and 400 mm high. Monolithic sections - reinforced concrete slabs with a thickness of 200 - 400 mm along beams with a cross section of up to 600 x 890 (h) mm and beamless monolithic sections of floors with a thickness of 600 mm. The material of monolithic sections of floors is concrete B30, B40. The covering of one-story underground attached premises is monolithic reinforced concrete beamless slabs 600 mm thick made of B40 concrete. The structures of one-story attached underground premises are designed taking into account the load from the fire truck. The covering of the multi-storey part of the building is H114-750-1.0 corrugated board along steel girders. The main load-bearing structures of the coating are a steel truss system in the form of a truss and a beam. The span of roof trusses is 16.2 m, the step is 4.05 m. The span of truss trusses is 8.1 m. The maximum span of metal welded beams is 24.3 m. The supporting structures of the roof in the second light zones are steel arched spatial structures with a span of 32.4 and 16.2 m. Steel C345, C255, C245. The spatial rigidity and stability of the building blocks is ensured by the joint work of the longitudinal frames, stiffening cores formed by the walls of the staircases, steel vertical braces, reinforced concrete stiffening diaphragms, rigid coupling of the columns with the foundation and hard disks of floors and roofs. The rigidity of floor disks made of prefabricated reinforced concrete slabs is ensured by sealing the joints between the slabs, the installation of a monolithic concrete block 80 mm thick from fine-grained concrete of class B20, the joint operation of the concrete block and slabs is ensured by anchoring with frames of A500C reinforcement in the seams of the floor slabs. The frames are welded to the embedded parts of the crossbars. The rigidity of the pavement disc is provided by a system of horizontal and vertical braces in the pavement level. The design of the stairs - prefabricated reinforced concrete steps on steel stringers, monolithic reinforced concrete platforms. Elevator shafts - monolithic reinforced concrete 200 mm thick, concrete B30. The calculation of the load-bearing structures of the building was carried out by specialists using the SCAD11.3 software package, taking into account the joint work of the building with the foundation. The calculation of the foundation was carried out by specialists using the SCAD11.3 software package The required fire resistance of reinforced concrete load-bearing structures is confirmed by calculations. The foundations are taken - on a natural basis in the form of monolithic reinforced concrete slabs with a thickness of 800 mm (under the main building) and 600 mm (in the parking area). Concrete B30, W8, F150. Concrete preparation is provided under the foundation. The relative mark of 0,000 corresponds to the absolute mark of +4,00. In accordance with the report on engineering and geological surveys, the foundations are the soils IGE-6, 8, 9, 12, 13A (loam, sandy loam, sand) with φ of at least 27 °, with at least 0,01 kg / cm2, E not less than 280 kg/cm2. The expected draft of the building does not exceed 5,3 cm. The designed building adjoins the existing RTP buildings. The buildings were surveyed, the category of technical condition is the second. There are no other buildings in the 30-meter zone. To determine the impact on the surrounding buildings, specialists carried out a geotechnical justification. The project provides for measures to protect the surrounding buildings: in the areas where the designed building adjoins the existing RTP buildings and in the area of ​​the foundation slab with rel. elev. bottom of the slab - (minus) 7.400; monitoring of the load-bearing structures of buildings in the surrounding area by a specialized organization in accordance with TSN 50-302-2004. The service life of load-bearing structures is 75 years. The service life of the outer wall structures is 50 years.
