What type of steel deck has shear connector devices?

The composite deck is specifically designed to act in conjunction with the concrete that is poured on it, allowing it to behave as a unified structural element. Shear connector devices, often in the form of welded studs or other types of connectors, are used to enhance the bond between the steel deck and the poured concrete, facilitating composite action. This connection is essential because it allows the combined system to carry greater loads compared to the steel deck or concrete acting independently.

In contrast, the roof deck primarily serves as a structural component that supports roofing materials and does not typically incorporate shear connectors with concrete. The cellular deck is designed with integrated voids for running electrical and mechanical systems, while the form deck is usually employed as a temporary formwork during the construction process, lacking the composite action that comes from shear connectors. The fundamental characteristic of the composite deck is its ability to utilize shear connectors to enable effective load transfer between materials, which is why it is the correct answer.
