I have the treated 6x6x16 posts installed, 3' deep and 8'-9' apart, in a 27x32 footprint, as shown. This was just going to be a simple pole barn, gable ends on each 27' side with a 4-12 pitch and 5 store-bought 28' trusses. But I've decided to make the structure twice as big, AFTER I have installed the posts shown in black. I need to enclose just the left side (shown), and lengthen the 27' gable ends to 54'. The trusses were going to span the 27' interior (plus a 6" overhang) with no interior support, but now, rather than go with trusses, I think I can just use two more posts for interior support, placing them as indicated in the drawing on the left side, and later add the additional posts, shown also in red, on the right side.
Suggestions? Is this design structurally strong enough using 2x8s where indicated in blue, and later in the same manner when I build the open side of the barn onthe right? Am I spanning too great a distance with 2x8s? Is there a better way of doing all of this now that I have the posts (shown in black) already installed?
