Steel framed building - typical bay size is 20'x20'.
Which is more economical for a roof framing system-
A. 1 1/2" roof deck on W10x12 at 6'-8" o.c.
B. 3" roof deck on W12x14 at 10'-0" o.c.
I think the 3" roof deck would be a better solution, even though 3" roof deck would cost more. You have fewer beams, (even though they are slightly heavier), fewer connections. Heavier roof deck would take more labor to install, but I'd imagine that would be at least offset by installing fewer beams.
Anyone have any thoughts or similar experience?
Thanks.
