I believe that the ground snow was set at 25 psf at least in the Chicago area.

Interesting to note though that in this code, by it’s own definition of live load Sectionsnow was considered a live load, different than what we view it now – it’s own separate load classification. W58.1 are provisions for unbalanced loading in the version. Here are the snow portions of Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.

They don’t change their building codes very often but they generate them by themselves. If you are working on a building designed under the review of the Chicago Building Department they have there own codes which are not derivative from any other code.
