Here is a link for the engineering of an attic truss. Note the splice
in the bottom chord. Note the bottom chord loading of 40 psf.
http://www.wsitruss.com/Prod_Frame.asp?Truss=A248. Why would you use
an attic truss if you couldn't use the space created for a room?

You need to learn to read a spec sheet. The bottom chord is designed
for a 10 psf live load (note 9).

That's for the bottom chord as a whole. For the room area (10-12) live
load is 40 psf. Wouldn't meet code in most places if it wasn't.
Again, attic trusses have been in use for many years. I gotta wonder
how much experience you have if you've never seen them.
