Existing Gypsum Deck
Existing Gypsum Deck
(OP)
Can anyone suggest some ways of evaluating the integrity of an existing gypsum roof deck from the 50's for updated gravity and uplift loads. I am sure the roof has had leaks over the years. No shop drawings are available.

The point load clearly checks the shear capacity and can be used to back-calculate a distributed load capacity.

This is not in an earthquake zone.
The gyp deck is part of a dome structure.

I evaluated some of these in the past. Water is a big enemy of theirs. They are also placed on top of drywall type board. They also use chicken wire type steel mesh.
SlideRule, let me know how I can get you the scans so you can add them to your web site.
