[ARSCLIST] Floor Load Capacity

[Nicole Blain <Nicole_Blain@xxxxxx>]

Hello all,
 
Does anyone know what the standards are for floor load capacity for stacks of 12" vinyl and 10" shellac discs.
 
The standard for library book stacks is ~150 pounds psf.  I tried and failed to find anything on the internet that specifies vinyl and/or shellac.  I imagine it would be higher for the latter.  If there's an official document or study out there too, it would help convince the architects/engineers that this is an important issue.
 
I found an article in the Fall 1993 ARSC Journal: Storage of Sound Recordings by Richard Warren Jr.  He has weight per linear foot, but not floor load capacity.  
 
Our collection houses ~175,000 12" vinyl and ~30,000 10" shellac discs.
 
Merci,
Nicole
