Suspended Concrete Floor Slab Design

The design of suspended floors should conform to requirements of aci 318 and aci 421 1r.

Suspended concrete floor slab design. This results in a cost savings in concrete of 25 50. The structural design of a concrete floor slab on grade is primarily controlled by the stresses caused by moving live loads and in some cases the stationary loads. They are normally pre fabricated offsite and transported by truck.

Concrete floor and slab construction 302 1r 3 the design of slabs on ground should conform to the recommendations of aci 360r. Some slabs have hollow channels running through them these hollow core slabs are used to help reduce weight and also to allow cabling and piping to be run through the slab. Slabs can be on ground suspended or a mix of both.

Concrete floor slabs on grade subjected to heavy loads c hapter 1. Refer to aci 223 for procedures for the design and construction of shrinkage compensating concrete slabs on ground. They can be insulated both underneath and on the edges.

A suspended concrete floor is a floor slab where its perimeter is or at least two of its opposite edges are supported on walls beams or columns that carry its self weight and imposed loading. Conventional concrete has high embodied energy. Slabs are classified into 16 types.

Stresses in floor slabs on grade. Concrete floor slab construction process. The slab may be supported by walls or by reinforced concrete beams usually cast monolithically with the slab or by structural steel beams or by columns or by the ground.

Suspended slabs are made of concrete and steel mesh the same as a ground slab. Suspended concrete slab suspended concrete slab is referred to a cement slab that is not in contact with the ground. Concrete floor slab construction process includes erection of formwork placement of reinforcement pouring compacting and finishing concrete and lastly removal of formwork and curing of concrete slab.
