What is composite floor construction?

Composite floors comprise slabs and beams acting compositely together.Composite slabs consist of profiled steel decking working together with in-situ reinforced concrete. The decking not only acts as permanent formwork to the concrete,but also provides sufficient shear bond with the concrete, so that the two materials act compositely together.
Although principally for use with steel frames, composite slabs can also be supported on brick, masonry or concrete components.
Composite floor beams are hot-rolled steel sections that act compositely with the slab.
Composite action is normally achieved by welding shear studs through the steel decking
and onto the top of the beams before pouring the concrete. The shear connectors provide sufficient longitudinal shear connection between the beam and the cured concrete so that they act together compositely.
Together composite slabs and beams produce structurally and resource efficient flooring systems for a range of applications.
