Gypsum-Fiber Roof Board - diaphragm capacity
(OP)
Anyone have experience with gypsum-fiber roof boards like USG Securock? Can I use this product over cold-formed steel framing for structural diaphragm? Do you they design values and/or code acceptance?

However, technically speaking, unless there is an ICC report on it the building code may not find it acceptable and thus you'd have to convince the building inspector/authority that it is OK to use.

The benefit in my experience is for fire ratings. Wood sheathing on steel framing is very acceptable structurally.
Make sure whatever you specify is rated as a Nailbase for your roofing materials (code approved). I don't think Fortocrete by USG is thus rated.
