Task

Variant No. 18000261

In accordance with the task, it is required to design a monolithic ribbed floor of a four-story industrial building with plan dimensions between the inner faces of the walls:

length L = 37.9 m,

width B = 24.3 m.

External walls - brick bearing 510 mm thick. Binding of layout axes to inner faces of walls is taken equal to 120 mm.

The height of the floors between the elevations of the clean floor: het = 4.5 m .

Window openings in the building :

width - 2.4 m,

height - 2.1 m.

Cross-sectional dimensions of monolithic reinforced concrete columns 400 × 400 mm.

Temporary standard load on all intermediate floors vn = 14 kN/m2, design pressure on the soil of the base R = 0.35 MPa.

Intermediate reinforced concrete floors are supported by external brick walls and internal reinforced concrete columns. Roofing is supported only by external walls. Prefabricated reinforced concrete trusses are used as bearing elements of the coating. Intermediate columns are led up only before interfloor overlapping of the fourth floor.

Concrete and reinforcement classes are selected by designers in accordance with the current regulatory documents.

The composition of the floor on the inter-floor floors and on the ground floor is accepted as standard, depending on the purpose of the room and the nature of the production technology in it.
