Choice of steel decking

In the process of steel structure design, how to choose steel decking?

The choice of the steel decking and its general layout are the responsibility of the structural designer, but the steel decking manufacturer can provide enough design data for the designer to make a decision. Designer must consider the fire resistance of the slab (which may depend on the type of steel decking), the ability of the steel decking and composite slab to resist applied loading, the propping requirements, and deflections at both the construction and in-service (composite) stages. And these performance steel deck manufacturers are very familiar with it, and have many years of steel deck supply experience. The structural designer can choose according to the engineering situation of the design and the product information of the floor deck.

Design data provided by steel deck manufacturers is often used to select decks because its performance is complex and best determined by testing. When structural designers choose the type of steel decking, they also need to consider the thickness of the project’s steel deck composite floor slab, the span of the steel beams of the steel frame, and the later use load. Then choose among the steel decking that meet the requirements of the project.

After the designer selects the type of steel deck, the data of the steel deck of this type needs to be substituted into the project for checking and calculation. Calculate according to the three stages of steel deck calculation, and the calculation results can only be used when they meet the requirements of local regulations. During this period, steel deck manufacturers need to cooperate with structural designers to issue relevant calculation documents according to the engineering situation.

The choice of steel deck mainly needs to be completed jointly by structural designers and steel deck manufacturers. Solideck has been cooperating with structural designers to complete the selection of steel decks and recommend steel deck products with safe structure and reasonable cost.
