I ended up with a 16' beam (8x16 concrete) with 2 #5s and 4 #7s in it.
It only carries a shingle roof on trusses.- Hide quoted text -

Oh, and the beam is not designed like that for what it "carries", but
for uplift from wind. And yes, for residential there are standard
designs, but not for industrial/commercial applications.

They are certainly looking at down force here since the #7s are on the
bottom and center with the #5 on top.

Well, of course in it's neutral state (no wind) there is downforce and
you therefore must have more reinforcing in the bottom because that
will be the tension face and the top would be the compression face.
Concrete doesn't perform well in tension, but in compression the
reinforcement is more for containment than anything. What did they
make you use for stirrups, #4's at 10" or so?
