Non-matching roof deck thicknesses
Non-matching roof deck thicknesses
(OP)
Does anyone know if it is acceptable practice to have two different metal roof deck thicknesses (1.5 inch and 3 inch) on a roof diaphragm in a single story, seismic design category D, SCBF building?
I have a portion of the building that would be advantageous to use 3 inch accoustical deck with a ceiling finish, and other areas where the structure will not be exposed.
Thoughts?

RE: Non-matching roof deck thicknesses
I am not fluent in seismic design but stiffness compatibility may be an issue depending on the rest of your structure.
You and the architect need to carefully coordinate details, if you have a parapet with scuppers for example..
