Howdy,

I got a question for you good people.

What do you all think of Chappell's "Single Arched Braced Truss"?
Has anyone built one of these? When looking at its strength my intuition is at a loss. Im assuming that the arches are in tension holding those feet together. I would think the pegging there should be offset to prevent one line of a tension on some grain. Other than that what do you all think of this configuration? Would some forged iron be needed here?

Conditions: (this is for you Mike, ;)): All things being equal
lets say 20' span





Anybody want to run through the members and tell me whats in compression and whats in tension, and...where the greatest magnitude of those forces would be?

Thanks
