Concrete On Metal Deck Slab

In the composite deck worksheet since the composite deck is interlocked or engaged with the concrete the deck is assumed to function as the positive moment bottom face slab reinforcing.

Concrete on metal deck slab.

Concrete slab on metal deck cracking. The transformed section properties are then used to determine the nominal bending moment and predicted deflections for the composite deck slab section. Suspended slab suspended concrete slab cement slab a quick and easier way to build suspended slab is to use metal deck if it s accessible. Engineers who design slabs on metal deck aren t thinking about the contractor.

Composite floor decks have embossments that grip the concrete slab and they are typically reinforced with rebar or wire mesh which creates a strong bond with the concrete floor. Composite floor decks are available in 1 1 2 2 or 3 depths. They don t have any real design guidance concerning deflection or crack control or how the tolerances can be different between the concrete and the steel. Composite steel deck is a permanent concrete form and provides positive reinforcement while it eliminates the time and cost of wood forming.

Composite floor decks are mostly used to create a composite structure with the concrete slab that is poured upon it. Casting the slab in strips parallel to the joists would eliminate negative moment cracking over the beams since the concrete would not have set and over the columns there would be a nice straight joint. 3 composite floor deck panels are primarily used for pouring concrete slabs. The determining factors for selecting the proper composite deck are the depth of the slab weight of the concrete normal weight or lightweight the support spacing and the uniform load you are trying to support.

This approach to suspended concrete slab construction is very common in commercial construction. Slab thickness is measured from bottom of ribs. Galvanized corrugated steel deck sheets for concrete slab yx51 250 750 is one kind of bondek sheets for multiple high rise buildings which is also called steel floor decking or bondek slab our quality composite decking sheets have full set of technical support. As a contractor therefore don t be afraid to talk to the engineer about all this.

The decking not only acts as permanent formwork to the concrete but also provides sufficient shear bond with the concrete so that when the concrete has gained strength the two materials act together compositely. The shear capacity of the composite deck alone is added to the beam shear capacity of the concrete to arrive at the total beam shear capacity of the slab.
