Architectural and space-planning solutions

 The designed logistics workshop is designed to accumulate and ensure uninterrupted shipment of products of a certain range to the customer. The logistics workshop is a one-story building with dimensions in the axes of 120,0 x 177,6 m and a height of 9,0 m to the bottom of the trusses. The building is attached to the northern facade of the existing logistics workshop of the first stage of construction. The floor mark is taken 1,2 m above the planning mark of the ground. The project does not provide for permanent jobs. Dressing rooms for service personnel and administrative premises are provided in the administrative building of the first stage of construction. External walls - horizontal "sandwich" panels with a polymer coating. Color color - RAL 7043. Plinth - reinforced concrete three-layer panels 300 mm thick and 1050 mm high, painted with smooth atmospheric paint. The roof is flat, rolled, with organized drainage of precipitation into internal drains. Light and aeration lamps used for smoke removal are designed on the roof.

Structural and space-planning solutions

The building of the logistics workshop (stage 2 of construction) is attached to the existing building of the first stage and is designed according to the frame-braced structural scheme with one-story, basement-free dimensions in the axes of 177,6 x 120,0 m. The building is divided by a deformation-sedimentary seam into two compartments. The height of the building is 12,6 m, the height to the bottom of the truss structures is 9,0 m. The frame columns are designed as prefabricated reinforced concrete, with a section of 500 x 500 mm, from VZO class concrete. The pitch of the columns is 24,0 x 24,0 m. Pairing of columns with foundations is provided rigid. The vertical connections between the columns are designed with metal portals along each longitudinal axis in each fire compartment. Transverse vertical connections are made of metal portals, two in each fire compartment. The under-rafter trusses are metal, with a span of 24,0 m, with hinged support on columns. The pitch of the truss trusses is 24,0 m. One block of horizontal braces is designed along the lower chords of the truss trusses in each fire compartment. Roof trusses are made of metal, with a span of 24,0 m, with hinged support on truss trusses. Rafter truss spacing - 6,0 m. Metal spacers with a pitch of 9,6 m are provided along the lower chords of truss trusses. The building is covered with galvanized steel profiled sheet H114-600-0,9 in accordance with GOST 24045-94. The fastening of sheets to roof trusses is assumed to be non-running, with the help of self-tapping screws in each wave. Fastening sheets of corrugated board between themselves is provided with the help of combined rivets with a pitch of 500 mm. The walls of the building are hinged on metal racks of half-timbered houses, made of metal panels of the "sandwich" type with a thickness of 100 mm. The spatial rigidity and stability of the building of the logistics workshop is ensured by the joint work of columns fixed in the foundations, vertical connections of the frame and the hard disk of the cover. The rigidity of the pavement disk is ensured by the corrugated pavement, which acts as a horizontal rigid diaphragm along the upper chords of the trusses, horizontal braces along the lower chords of the truss trusses, and horizontal braces along the lower chords of the truss trusses. The calculation of load-bearing structures and foundations was performed using the SCAD 11.1 design and computer complex without taking into account the joint action of the “building-foundation-foundation” system. For a relative mark of 0,000, the mark of the finished floor of the building is taken, corresponding to the absolute mark of 17,600 m in the Baltic system of heights. The foundations of the building are designed as piled, free-standing, columnar foundations for frame columns and strip foundations for half-timbered racks. The piles are bored, immersed according to FUNDEX technology, 8,1 m and 6,1 m long, 400 mm in diameter, with a lost tip 540 mm in diameter, made of B20, W6, F150 class concrete. Grills are taken as monolithic reinforced concrete, made of concrete of class B20, W6, F150. The connection of piles with grillages is accepted as rigid. Under the grillage there is a preparation of class B7,5 concrete with a thickness of 100 mm and a cushion of crushed stone with a thickness of 200 mm. In accordance with the “Technical report on engineering and geological surveys for the development of a project for the construction of a logistics complex ...”, light silty, hard, dislocated, greenish-gray clays, with interlayers of sandstones of low strength and medium strength, with gruss, sandstones with interlayers of silty, wet sands (layer IGE-7) with the following design characteristics: p = 2,14 g/cm3, e = 0,525,  = 17°, IL = -0,35, c = 0,08 MPa, E = 24 MPa. The bearing capacity of piles according to the results of static sounding is 80,2 tf. The design load allowed on the pile, taking into account the reliability factor Yk = 1,25, is 64,1 tf. The maximum design load on the pile from the building will not exceed 51,0 tf. To clarify the bearing capacity of piles, the project provides for testing of piles with a static indentation load before the start of mass immersion. The average calculated expected settlement of the building is 25 mm. The normative depth of seasonal freezing of soils is: for loams - 1,14 m, for fine sands and sandy loams - 1,39 m, for gravel and medium-sized sands - 1,49 m. Groundwater - non-pressure, found at depths of 0,1 m ÷ 1,2 m.
