Metal Deck
(OP)
Does anyone have suggestions on design references for calculating the allowable concentrated loads for non composite metal decks? I checked out the SDI website and only found a design guide for composite decks.
Thanks in advance

I guess the concentrated load capacity would depend on the
distribution mechanics of the load (i.e plank, rail, wheel), as well as the load location (on top of rib, or in the valley).
Is the general approach to supply another structural member (flat channel or angle) that can span between supports and
just ignore the deck?

You might frame below the decking to accommodate the weight of the unit and also reinforce the opening in the roof if there is one. Typically this is accomplished with angles or channels between joists/beams.
Or you could frame a 'base' above the roof as you mentioned. Typically, if your metal deck rests on OWSJ's you would design a base to span accross 2 or more joists (Depending on the load, etc). Just make sure the joist supplier knows your intentions!
