Metal Deck as Flexible Diaphragm
Metal Deck as Flexible Diaphragm
(OP)
I am designing a very small building, 22 ft by 7'-8" actually. The structure will be CMU and have type B roof deck. My question is, because the span is so small, is it common to use deck only as a flexible diaphragm - by which I mean no joists no beams? I am going to use 7'-8" as the span and select fastener layout per SDI.
Thanks in advance!

RE: Metal Deck as Flexible Diaphragm
It isn't a "diaphragm" question here - just a strength/stability question.
Perhaps a 3" deep roof deck? For simple spans of 7'-8" you can use a 22 gage.

Spanning the deck without intermediate support sounds like an economical solution. Just ensure that you still meet Factory Mutual requirements etc.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
