Hello
Anybody ever come across this situation?
What connection devices would be used at the rafter-to-foot beam?
I am trying to solve this for my brother’s home plan.
It is important that the inside edge of the rafter end at the bottom edge
of foot beam for drywalling over.
I can give more details, more “drawings”, or just plain make this
thing more clear, if it is not clear enough.
Thanks,
patwig

Every I-joist manufacturer has connection details on their websites. That would probably be the best place to check.
Why does it matter if the bottom of the I-joists meets the bottom of the beam? You probably haev a lot of tolerance if you're drywalling over it.
Thanks
the bottom of the beam is the same plane as the bottom chords of the trusses nearby.
I'll try to get some more info from the simpson site. patwig
So
I got in touch with the weyerhaeuser rep : [email protected]
Got fast service, put me in touch with their "structural frame engineer"
He came up with a hanger that would work in this situation.
I gotta say, Me Very Happy.
It was not possible, from all the lit. that I looked at, to find this thing.
Thanks,
Pat
Foot beam? Never heard that one before...
Anyway, is this "foot beam" sitting on top of a wall or what? What is it made out of? OSB rim board? Dimensional lumber? LVL?
Also, could you please clarify:
>> It is important that the inside edge of the rafter end at the bottom edge

I'm guessing that the configuration is a vaulted ceiling mixed in with a trussed roof?
thanks.
"parallam" beam.
I call it foot beam cause it's at the foot of the rafter.
It is supported at each end, spans 13'
and has to hold the foot of each rafter at 2' intervals over that length.
vaulted ceiling transitioning to flat ceiling without an exposed beam at the transition.
Hope it helps.

Here's a view.
The green beam is the one.

Let's call it a flush beam. The I-joists need to be hangered and the exact hanger needs to be specified on a drawing provided by the I-joist mfg/supplier or an engineer. Even if we knew what width I joists they are, you still need to go the "official" route. When you buy the I-joists they will provide you with a drawing that will specify the hanger and they will supply them too. This will probably all be done by the truss company, or at least the truss companies I deal with tell me they supply all or nothing, (for a roof system) and they supply the stamped drawings too. My truss company would supply the LVL too.
Edit: I just saw your pervious post where you said you contacted wherhauser (sp?). My above comments still apply though. Your truss company will provide an overall design for the roof.
