Structural and space-planning solutions

The level of responsibility of the building is normal. Classstructures – KS-2. Geotechnical category of the building – 2. Windy area II, terrain type B, snowy area III.The building is designed with a frame-wall structural design with load-bearing structures made of monolithic reinforced concrete. Buildingdesigned from four blocks. Blocks 2 and 3 are adjacent to each other, blocks 1 and 4 are separated from blocks 2 and 3 and are connected to them by transitions. Transitionsseparated from the blocks by sedimentary seams. The blocks are additionally separated by temperature-sedimentation joints.Concrete of monolithic structures of the above-ground part of the building and internal structures of the underground part of the building - B30 F75, working fittings – A500S.Concrete of external monolithic structures of the underground partbuildings – B30 W8 F150, working fittings – A500S.Non-load-bearing external walls of blocks - made of expanded clay concrete blocks D850 B3.5 with external insulation and finishing with facade systemwith an air gap device.Load-bearing external walls are made of monolithic reinforced concrete with a thickness200 mm with insulation and finishing similar to non-load-bearing walls.The outer walls of the basement and plinth are 200 mm thick, in the area of ​​​​supporting the columns of the first floor with pilasters, with external insulation.The parapet walls are made of monolithic reinforced concrete 200 mm thick with insulation on both sides and finished like non-load-bearing walls.Columns - section 400x400 mm (in the basement - 500x500 mm)made of monolithic reinforced concrete. Internal load-bearing walls – 200 mm thick made of monolithicreinforced concrete. Floors and coverings are 200 mm thick slabs made of monolithic reinforced concrete.
