Composite steel assemblies are an efficient and popular structural option for floor construction. Figure 1 shows a typical assembly, consisting of a steel beam, metal deck, concrete slab, and shear connectors. The composite action between the steel beam and concrete provided by shear connectors creates the composite properties that make the system a very stiff and strong structural element.
