Max SDI Construction Span
Max SDI Construction Span
(OP)
My question is simply this. If SDI limits construction spans to a certain maximum span, is ther any practical application of a cold-formed steel deck beyond this span. For example: 20 ga B-deck 3 span condition can tolerate 53 psf for equal spans of 8'-6", but max SDI construction span limits you to 7'-9". The way I interpret this is that no matter what the capacity of the deck may be, you are never allowed to go beyond the max construction span. I am primarily talking about situations where the steel deck is the roof.

Most always, shoring is a higher expense than increasing the gage.

But to an extent, the tables that go way out there to large spans are probably not used that much for practical and cost reasons...but they may provide design information for other uses besides "roof" deck.
