1970s MBMA

[structSU10]

Shot in the dark here - does anyone have a copy of the snow provisions from the MBMA in the 1970's? Original drawings reference this for snow loading and I want to understand the snow drift load they may have taken into account as the area was planned for an expansion that is finally set to happen.

I got the 1981 Manual. Skimming over the snow drift it looks basically the same as what ASCE7 has been doing for years. Also MBMA Manuals generally don't do anything novel. They just collate the relevant publications (ASCE7, IBC, etc) into one book.
