Chapter 16 structural design. 2018 international building code. Use our roof snow load calculator to determine your design roof snow loads. Purpose of this web site.

2018 international building code. The purpose of this web site is to provide ground snow load analysis information and data gathered from all 50 states. There are of course special cases like deep drift loads on large flat roofs. If the snow weighs 10 pounds per cubic foot and there are 1 5 feet on the roof each square foot of the roof is getting 15 pounds of pressure.

If you need to gather ground snow load data programmatically please consider our api service. For additional questions or concerns about specific ground snow loads please call us at 1 425 741 5555. The publication is 20 and may be purchased from msu civil engineering at 406 994 2111. Each state has a listing of building code and applicable guidelines for snow loads as well as details about where the snow load information may be found or purchased.

In other words on a steep roof less material would be stacked in a concentrated area at one time to avoid having it slide off. P s c s p f where.
