3.1.3 Roof Snow Load vs. Ground Snow Load
The Roof Design Capacity tables reflect roof snow load (RSL) values. These are design values. Often,
comparisons are made to ground snow values (GSL). These are not the same. The conversion from GSL to RSL
varies between jurisdictions and is governed by building codes:
• In the United States, for grain bins, GSL = RSL x 2
• In Europe, for grain bins, GSL = RSL x 1.25
