General provisions

Space-planning and structural solutions of buildings should exclude the possibility of injuries by people during movement, work, use of mobile devices, technological and engineering equipment, reduced dynamic effects on building structures, technological processes and workers caused by vibration-active equipment or external vibration sources.

In this course work, a one-story industrial building was designed:

- by volume planning: two-span;

- by equipment of lifting and transportation equipment:

unit A - bridge crane;

unit B - bridge crane;

- by lighting type: with combined;

- by air exchange system: with mechanical ventilation;

- by the presence of heating systems: heated.

Load-bearing structural system of buildings consists of foundations, columns, load-bearing structures and slabs of coatings, crane beams and links. The structural scheme of the building framework is determined on the basis of the analysis of architectural and structural solutions. Spatial rigidity and stability of the frame is ensured by the combined operation of vertical and horizontal structural elements.

Constructive solution

4.1 Structural diagram

The frame of single-storey buildings with a coating of flat elements consists of transverse frames formed by reinforced concrete columns rigidly embedded in the foundations and hinged on the columns by rafters and reinforced concrete trusses, and longitudinal frames formed by crane beams, railway trusses, a rigid coating disk and steel bonds.

The hard coating disk is formed by coating plates welded to rafter trusses or beams with subsequent grouting of the seams. Paving slabs - lightweight concrete panels for unheated rooms.

4.2.3 Columns

The frame consists of transverse frames formed by columns secured in foundations and hingedly supporting rafter trusses on the columns.

Columns are selected taking into account spans, height of the building and lifting capacity of cranes.

The following columns are designed in the building:

by section type: solid cross section,

crane equipment availability: crane;

by the presence of a passage in the level of the crane path: without a passage,

by the number of consoles: single-console;

according to the purpose of the fachverka: ordinary and end.

By carrying capacity: 20/5 t

The columns are located in blocks A with a pitch of 12 m with a reference at the ends of the building 500 and a reference to the longitudinal axis 250 (axis 1 and 2). In block B, the columns are located at a pitch of 12 m with a reference at the ends of building 500 and a reference to longitudinal axis 300. To connect to the foundation, the column is brought into the sleeve to a depth of 1.00 m in block A and to a depth of 1.35 m in block B.

Along the outline of the building there are reinforced concrete fuselage columns with a pitch of 6 m.
