Roof diaphragm ratio for non-structural penthouse
Roof diaphragm ratio for non-structural penthouse
(OP)
I need to design a roof penthouse for a stair. The penthouse is small with 21 ft long and 3.75 wide. I think this penthouse can be designed as a non-structural component based on the CBC code. Do I still need meet the allowable diaphragm ratio 4:1? If so, what can I do to meet the diaphragm 4:1 ratio besides shorten the length?
Thanks for your help!

If it's wood, I suppose that you could prefab or site build a flat truss to lay horizontal under or over the framing. It won't be working too hard.
