Is there a difference between composite and non-composite design?
A. Yes, in composite design of floor systems the concrete is working with a steel beam in providing structural support. Shear connectors are welded to the top surface of the upper steel flange fixed either through metal decking or on either side of precast floor units over which concrete is then poured. In non-composite design the concrete slabs are providing just a floor and is just dead weight. Some types of columns can also be designed for composite action in which a steel section may be encased in concrete with shear connectors, concrete columns cast containing reinforcing bars or infilling hollow sections with concrete and reinforcing bars or steel fibres.
