Resumo(s)
A composite steel-concrete slab consists of a concrete topping cast on the top of a profiled steel
deck. Normally, the concrete is reinforced with an anti-crack mesh positioned on the upper part
and individual reinforcing bars placed within the ribs, see Figure 1. The steel deck acts as a
permanent formwork and the composite action between the steel and concrete is generally
achieved by indentations or embossments in the steel deck. Due to the reinforcement provided
by the steel deck, composite slabs are generally slenderer and more efficient than flat concrete
slabs because require less additional reinforcement and less concrete as well. The reduction of
the construction time, simplicity of installation and reduction/elimination of struts are other
advantages of composite slabs that should be highlighted.
