Subject: Design compotents of a gambrel roof?

I am in the process of designing a gambrel roof style barn and need the max spans, angles, supports, etc.
The barn is 28' wide and 32' long with frame construction of 8" x 8" on 10' centers. The roofing material planned is a metal raised seam roof. The "attic" area will be used as living quarters. It will not be a clear span of 28'. 8"x8" support post will be 8' off both walls leaving a 12' span between the two support post.
I am looking for a layout to build the gambrel trusses.

The snow load factor is little to no effect, for the barn will be built in Georgia.

The barn is 10' wide and 12' long with frame construction of 2" x 4" on 2' centers. The roofing material planned is a shingled roof.
