Scissor truss intersection
Scissor truss intersection
(OP)
I'm in the process of designing my own barn with scissor trusses. The barn has a floorplan like a + sign, which means two wings with a 90 degrees intersection in the center. Both barn wings should be done with scissor trusses and are 36' respective 40' wide. Here my questions now: Can scissor trusses intersect in a way, that the ceiling goes up in the center to the top ridge ? Can there be a cupola in the center ?

1) You'll need a heel depth and roof / ceiling pitches that make the central girder possible. Talk to a truss fabricator.
2) This solution assumes that you don't mind having some trusses below your cupola.
3) I expect that this would be a very economical solution relative to hand framing. Of course, I have an obvious bias.

RontheRedneck: I think we have some depth to work with. KootK did not already take the challenge.
KootK: Thanks for your draft and the time you invested into this. However,
why the trusses have to be under the cupol ? The square cupola structure could sit like a keystone on top of the trusses in my opinion. Any reason why this would not work ?
Regards and thsnks for all your help.

I'm just travelling and can't scan anything, but what I imagine is 4 pieces of your part "C" (right bottom of your drawing), instead of one part "B" and 2 parts "C" connected to it in the center. Can't 4 "C"s be connected to the corners of a square cupola Cuboid in the center? Such a cuboid would also provide the depth to work with for the parts you marked "D".

Maybe with a cupola framed in steel with some big money connections you could swing it. I don't see you ponying up that kind of dough for a barn though.

KootK, I'm not saying your way of doing it is wrong. It's just not the way I would do it.

Has anybody an idea which engineer or truss company in Florida (Sarasota/Bradenton area) could do this ?
