In addition to acting as a form deck (shuttering) during the construction period, composite deck sheets substitute the tensile reinforcement in the concrete slab. This is made possible by the composite action developed between two dissimilar materials like concrete and steel by the provision of shear connectors at the interface of the two materials. These shear connectors are embossments in the deck sheets in typical pattern unique to each profile. These embossments develop friction as well as mechanical interlock between the concrete and steel sheet. These two reactions take care of longitudinal shear developed at the interface of the concrete and steel sheet, preventing sliP. and thereby enabling the two materials to act as a single entity of composite deck. To ensure friction at the embossments, there should not be any paint or grease on the sheet surface in contact with concrete nor should any vibrating load be permitted to act on the slab untill the concrete has set completely and composite action has developed. The friction between the steel sheet and concrete is expressed by a co-efficient denoted as "k" while the mechanical interlocking between steel and concrete made effective by the embossments is denoted by "m". The design of the composite slab is entirely governed by these two coefficients "m" and "k" which are also known as the shear-bond values of a composite deck sheet. It is not enough merely to incorporate the embossments on a profiled sheet to proclaim composite slab action. Each profile with its embossment is unique and will have its own unique shear-bond value. This unique shear-bond value is mandatorily to be established through extensive laboratory tests (BS 5950 : Part 4, EUROCODE 3) as per guidelines laid down in the standard before the profile can qualify as a true, established composite deck sheet.
