Floor Slab Design Uk

The structural design of the concrete floor slab on ground is dominated by the sub grade conditions and the floor loadings.

Floor slab design uk.

It may form the floor of a basement at ground level or at upper levels. The concrete floor slab itself provides structural support for floor loads and suitable backup for floor coverings and finishes. Floor classifications table 1 describes the nine classes of concrete floors according to aci 302 guide to concrete floor and slab construction. If consolidation of plastic soils is determined to be a potential problem a suspended slab may be the only effective solution in which.

For larger floors there is a need to have joints within them in order to avoid the development of cracks within the floor slab. The floor slabs joint details will be provided because they are significant part of the slab design. The floors may need to be thickened beneath the column positions in order to fix the holding down bolts. Concrete is a composite material consisting mainly of portland cement water and aggregate gravel sand or rock.

The term floor slab usually refers to a floor that has been formed using concrete and generally steel reinforcement and may form part of the structure of a building. Ground bearing floors shall be of adequate strength and durability and use concrete mixed and reinforced as necessary to support floor loads safely and resist chemical and frost action.

It will be typically reinforced either by rebar or steel fibres. Another factor that influences the design and specification of ground bearing concrete floors is the nature of the load that they have to support. 6 4 5 equ6 52 8 5. When these materials are mixed together they form a workable paste which then gradually hardens over time.

Concrete slab design proceduredesign of continuous slab basics of reinforced concrete slab design slabs are generally designed on the assumption that they consists of a number of beams of breadth one meter. Effective span of slab2.

This table details some of the special considerations and finishing techniques that are appropriate for each class of floor. The two design options are a ground bearing slab or a pile supported suspended slab. Mix joint design and performance and the slab thickness. It is an important construction material used extensively in buildings bridges.
