When framing a gambrel roof we always use a Load Bearing Ridge Beam with Load Bearing Purlins to support a gambrel roof structure or use Collar Ties on each side of rafters at the hip joint between the upper and lower rafters. I was recently talking to a builder that had told me that he was going to use a Load Bearing Ridge Beam without the Load Bearing Purlins or Collar ties, or Gusset Plates at the hip joint of the upper a lower rafters, I told him I didn’t think that was a good idea not support the joint between the upper and lower rafters. Has anyone ever built or seen a gambrel built using a Load Bearing Ridge Beam without the Load Bearing Purlins or Collar Ties or Gusset Plates support the hip joint?

Not exactly sure what you mean by "Load bearing purlins"
Guess I could take the easy route and say just use trusses - They'll solve all you problems..................(-:
As long as there are tests, there will be prayer in public schools.
Boss, some people put a wall there to support the uppr rafters. This "purlin" would effectively be a beam replacing such a wall for open space.
I was thinking truss too. It's hard for me to imagine how the builder could pull this off. I'll be gnawing on it while I gnaw on turkey bones..
