 Structural and space-planning solutions

The structural scheme of the residential building is cross-walled. The building was designed from two volumes (from a 24-story residential building and a one-story mechanized 11-level car park), separated by a 150 mm wide expansion joint with a mineral slab. The residential building from the 1st to the 15th floor inclusive is designed with monolithic load-bearing structures, above - from prefabricated elements. Indoor and outdoor prefabricated wall panels - custom-made, manufactured by CJSC "Betset". The design documentation for the panel was developed by Sormunen & Timonen LLC in accordance with the loads of an individual residential building. All aboveground and underground supporting structures are designed from monolithic reinforced concrete, concrete B30, W6, F100, working reinforcement A500s and B500. Prefabricated reinforced concrete internal structures - from concrete B30, W4, outer shells of facade walls - B25, W6, F100. Non-bearing external walls of the building from the 1st to the 15th floor inclusive - multi-layer, with a total thickness of 320 mm and 420 mm, consisting of aerated concrete blocks D500, B2,5, F35 200 and 300 mm thick, a layer of Rockwool insulation 100 mm thick and a layer of plaster 20 mm. Fastening of insulation to aerated concrete - with dish-shaped dowels, fastening of aerated concrete to reinforced concrete of load-bearing structures - with stainless steel anchors. The load-bearing external walls of the building from the 1st to the 15th floor inclusive - from monolithic reinforced concrete 250 mm thick with insulation and plastering as non-bearing walls. Non-bearing external walls of the building from the 16th floor - prefabricated reinforced concrete hinged three-layer panels 350 mm thick, inner shell 100 mm thick, middle layer of insulation 170 mm thick, outer shell - 80 mm thick. The load-bearing outer walls of the building from the 16th floor are prefabricated reinforced concrete three-layer panels 410 mm thick, the inner shell is 160 mm thick, the middle insulation layer is 170 mm thick, the outer shell is 80 mm thick. Connection of layers in three-layer external panels - reinforcing cages. All panel connections are without welding. The vertical junction of the outer panels with each other and with the inner panels is rigid, keyed-loop, with embedding loop outlets from reinforcement with a diameter of 10 A500C (the pitch of the outlets and keys is 450 mm) from the inner layer of the panels, united by vertical reinforcement with a diameter of 12 A-III. Concrete B30. The horizontal joint of the outer panels is closed, sealed with mastic, with the fixation of the inner layer of the top panel on the reinforcing outlets 16 A500C and 12 A500C (the pitch of the outlets is 1,2 m) from the wall panel of the previous floor passing through the floor slab. The outer walls of the basement floor are load-bearing, 250 mm thick with external insulation with a layer of foam. Internal walls from the 1st to the 15th floor inclusive - 250 mm thick (in the basement in the area of ​​columns with widening in the form of a circle with a diameter of up to 400 mm). Conjugation of monolithic walls in the intersection area - on dowels. Internal walls from the 16th to the 23rd floor inclusive - from prefabricated reinforced concrete panels with a thickness of 160 mm. The vertical joint of the internal panels is rigid, keyed-loop, with embedding of loop outlets from reinforcement 10 A500C (pitch of outlets and keys - 450 mm), united by vertical reinforcement with a diameter of 12 A-III. Concrete B30. Joint width 70-100 mm. The horizontal joint of the internal panels is a platform joint with fixation of the panel of the next floor on the reinforcing outlets 16 A500C and 12 A500C (the pitch of the outlets is 1,2 m) from the wall panel of the previous floor, passing through the floor slab. Keyed joints are designed with the perception of shear forces by concrete, without taking into account the resistance of the reinforcement. The maximum design force in the key (taking into account the forces of progressive destruction) will not exceed 29,1 kN with a key strength of 37,78 kN. Columns in the first floor along the "Y" axis - with a diameter of 400 mm. Ceilings and covering - flat continuous slabs 200 mm thick, in the area of ​​​​balconies - with thermal inserts. Elevator shafts - from prefabricated reinforced concrete panels of individual production with a thickness of 200 mm. The flight of stairs and lintels are prefabricated reinforced concrete. Ventilation blocks - prefabricated reinforced concrete, with floor-by-floor support on floor slabs. The spatial rigidity and stability of the building is ensured by the box-shaped structure of the basement and the joint work of load-bearing walls and columns with rigid disks of monolithic floors. Calculations of building structures were made in the spatial model "building - foundations - base" on the software package "SCAD" v.11.1. The calculation confirmed the stability of the building against progressive destruction in the case of local destruction. The calculation confirmed the fire resistance of the building. The class of responsibility of the building is the second (normal). The service life of the building is at least 50 years. The enclosing structures of the building for the placement of the automated car park equipment were designed in accordance with the Design Assignment, taking into account the absence of any force transfer from the equipment to the walls and covering of the building. The loads on the grillage are taken in accordance with the installation drawings of equipment manufactured by a Korean company. The structural scheme of the attached automated parking lot is a wall one. All supporting structures are made of monolithic reinforced concrete, concrete B30, W6, F100, working reinforcement A500s and B500. Walls - 250 mm thick. The cover is a ribbed plate (ribs up) 200 mm thick, designed to absorb loads from a rooftop boiler. Ribs - with a section of 400 x 600 (h) mm with a maximum step of 3,58 m. External stairs - a steel structure with fastening platforms to reinforced concrete walls on brackets. Platforms - from closed bent-welded profiles. Stringers - from rolled channels supported by platforms. The calculations of the car park structures were made using the SCAD v.11.1 software package. Roof block boiler house - designed from three blocks of full factory prefabrication, interconnected in the design position - with bolts. The frame of the blocks is post-beam.
