Composite construction has contributed significantly to the dominance of steel frames in the commercial building sector worldwide.
Composite floors are usually incorporated into multi-storey commercial structures and typically consist of profiled steel decking with a reinforced concrete floor cast in-situ. The decking not only acts as a permanent shutter, but it also provides sufficient shear-bond with the concrete by means of the shear-studs, so that when the concrete has gained sufficient strength the two materials act ‘compositely’, hence it is known as a ‘composite floor’.
The composite action is achieved by means of shear-studs which are welded through the decking to the top flange of the supporting steelwork by means of thro-deck welding. These shear studs provide sufficient shear connection between the concrete and the steel floor so that they act together structurally. Openings may be incorporated into the floor for stairways, elevator shafts, and service wells.
There are many benefits to be gained from this method of construction, some of which include:
