This slab system is composed of a beam and slab composite. A composite slab, consisting of profiled steel sheet and reinforced concrete layer, is combined with a steel composite girder. This is also referred to as classic steel composite construction, as all components of the ceiling are composite components.
The composite slab, consisting of profiled sheet metal and reinforced concrete layer, is poured with the steel beam using composite agents, usually head bolts, in a rigid manner. It thus forms the upper chord of the steel composite girder.
In the case of slabs with a continuous effect, additional reinforcement is inserted in the area of the composite girder. For ceilings without continuous effect and in the edge area of the ceiling, a minimum support depth of 75 mm is prescribed for steel and concrete, and at least 100 mm for overlays on other materials. The steel profile can sit below the reinforced concrete plane, but may also be integrated into it. In this case, the profiled sheets, here without a continuous effect, attach to the side of the steel profile.
Composite beam systems are regulated in Eurocode 4. Composite beams used in combination with composite ceilings require general building authority approval. This ceiling system is primarily used in commercial and industrial construction. Examples of applications include multi-storey car parks or steel structures that require large spans.
