Re: Joints in concrete floor slab on bar joists

[Subject Prev][Subject Next][Thread Prev][Thread Next]
If not the deck alone should carry approx 216psf load. Sounds like the
cracking may be related more to the concrete. Maybe a bad mix or cement /H2O

I don't know what your live load criteria is but my hunch is that when you
run the numbers the slab section will check as an unreinforced section under
the provisions of ACI 318 Structural Plain Concrete.

Thank you for the reply regarding the slab problem.

The slab is on light metal slabform spanning two feet between bar joists.
How would you add sub framing?  It would be tough.
The same with external reinforcement.
