I a58.11 that the ground snow was set at 25 psf at least in the Chicago area. Thank you for helping keep Eng-Tips Forums free from inappropriate posts.
I am attempting to review the design loads used on an older building designed in which was using ANSI A They don’t change their building codes very often but they generate them by themselves. I cannot find any copies of this old code so any help would be appreciated.

I am trying to find out how flat roof snow ansl were determined and what provisions were in place if any to account for unbalanced snow loading. Register now while it’s still free!
I also noted in the a that there is an exception to the alternate span loading requirement that may or may not apply in Chicago – “Alternate span loading need not be considered where a5.1 uniform roof live load is 20 psf or more and the provisions of Section c are met.
