Construction: Composite floor system: training video from the Corus BCSA training pack.
“Composite floor slabs generally comprise profiled steel floor deck with in-situ concrete cast over the deck.
The deck acts as permanent shuttering and spans in a direction transverse to the secondary beams.
Primary and secondary beams in composite steel frames are rigidly connected to the floor slabs by ‘shear studs’, which are connected to the beams by through-deck welding techniques.
This allows the floor slab and the beams beneath to act compositely.
Beam depths are therefore less than any equivalent non-composite frames.”
