Design of precast concrete structures for a multi-storey industrial building

Structural elements of a multi-storey industrial building with an incomplete frame are being designed, which is a system of columns and transoms connected in structural nodes into a rigid and stable spatial system that absorbs vertical loads. External load-bearing walls that absorb loads from their own weight, roof and floor elements, as well as wind load, perform the function of stiffening diaphragms. 

The length of the building is 60 m. The grid of columns is 6×6 m. Crossbars are located across the building, ensuring its spatial rigidity. 

Binding of the internal surfaces of the walls to the axes – 200 mm, the platform for supporting the transom on the wall – 250 mm, on the columns – 250 mm, the platform for supporting the floor slab on the walls – 120 mm, on the transoms – 120 mm.

The type of slabs is ribbed without transverse intermediate ribs. An ordinary floor slab P-4 has nominal dimensions in the plan - 6000 x 1500 mm.
