Tension Ring for eight sided structure
Tension Ring for eight sided structure
(OP)
Does anyone have any suggestions for detailing tension ring for supporting eight-sided roof structure. The structure is only 14' wide with an 8/12 roof pitch. I've detailed similar projects with plywood gussets at the corners. Just looking for new ideas!
Thanks
Thanks

On larger tension rings, I have designed a stell plate to act as a horizontal plate that is bolted to the top plate, and had an angle welded at the corner to resist the thrust.
On some smaller ones, I useed continuous sSimpson straps to wrap the structure. Using this , I have specified a minimum lap splice dimension and minimum number of nails at the splice.
I have also used the top plates to transferthe thrust and reinforced the corners with small steel plates and/or plywood.

The compression ring was set on some blocking off of a scafold. When the framing was complete, we tensioned the cable and the roof lifted slightly and the blocking fell out. The building receives significant snow load every year and it has been functioning for almost 35 years.
