ANSI A58.1 - 1972 Snow Loads
ANSI A58.1 - 1972 Snow Loads
(OP)
I am trying to find out how flat roof snow loads were determined and what provisions were in place (if any) to account for unbalanced snow loading. I believe that the ground snow was set at 25 psf at least in the Chicago area. I cannot find any copies of this old code so any help would be appreciated.

You will need to find a library which has older Code books available. They don't change their building codes very often but they generate them by themselves.

Interesting to note though that in this code, by it's own definition of live load (Section 2301), snow was considered a live load, different than what we view it now - it's own separate load classification.
