Industrial Mezz in SDC D

[MOPE]

Using ASCE 7-10, SDC D, we have an industrial mezzanine with a DL < 20 psf, height = 20 ft., which requires 3 to 4 ft trusses due to long spans. What is your opinion based on code if OMF is allowed? The allowance in ASCE 7 allows it for a roof with DL < 20 psf and height < 65 ft. A mezzanine is not a roof, but could this allowance justify the use of an OMF for a single story mezzanine?

You micht be able to make a case for this if the mezzanine structure was no part of the main building structure under 12.2.5.7. Otherwise, no.

The mezz is to be installed in an existing industrial facility and is independent of the existing structure.
