RE: steeldek slabs

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Several years ago, I had some questions about this myself.  If you are
referring to composite deck slabs, they are designed as one way simple span
slabs.  The values in the deck catalogues were predicated on testing.  They
generally perform quite well with no objectionable cracking.  The WWF (mesh)
is for drying shrinkage crack control only, and the location of the WWF is
not critical.
Slabs on non-composite form deck require WWF (mesh) to develop the
structural loads indicated in the catalogues.  The location of the WWF
(draped or undraped) is critical to achieve the loading indicated, but I
have yet to see it placed correctly.  This WWF is structural.

Hello .
Has anybody designed and implemented continuous one way steeldeck slabs on
concrete beams where the slabs are designed as a series on simple span slabs
with no negative reinforcement on top of  concrete beam support.
I would like your comments on the performance of these slabs after
Thanks in advance.
