To me, the most unique part of this frame is that the tails of the rafters are joined to either a full tie beam that rests on top of the sidewall top-plate, or for lack of a better description, "stub-tie-beams", which then seem to be attached to a beam that spans the bay and connects the full tie-beams about 24" from their ends. It seems like the framer is using this secondary beam to help control the roof from pushing the sidewalls out at the top. Do you also see this?...or is there a different purpose or idea behind this additional framing system?

Thanks,
