Designing slab on metal deck
Designing slab on metal deck
(OP)
Hey all,
How's it going? My first post.
I'm designing a mezzanine structure with a slab on metal deck. I'm planning on using a non composite deck, 1.5 inch. I'm trying to reduce the DL as much as possible and am thinking I can get away with a lower thickness slab if I go with a composite deck. Is there any advantage to using composite decking as opposed to non composite besides longer spans? I'm assuming the composite decking is more expensive?
Thanks

1) Typically excellent manufacturer support - the software is often very good/intuitive, and typical details are available in product literature.
2) The tin itself provides a permanent platform to work on, and does not require temporary formwork etc.
I'm not sure about cost, but I think the first two advantages really sold it for my senior engineer. Check out the SCI guide P300 composite decking for a good practical reference on the subject.

I assume you are considering 1 5" composite deck versus 9/16" form deck.
Call a deck broker/supplier for prices.

For thinner conc. decks you can always spray fireproofing on the steel but that may not be the most economical.
