How do you find a ground snow load?
How do you find a ground snow load?
Snow load calculations for most residential structures are usually performed using the following method:
- Determine ground snow load based on location and elevation.
- Calculate flat roof snow load pf using the following equation: pf = 0.7CeCtIspg
- Check low sloped roofs for minimum snow load as per ASCE Sec.
What is the ground snow load?
The ground snow load is pretty much what it sounds like: A predictable load situation that is derived from snowfall records over the years in a particular region (photo 2).
What is the difference between ground snow load and roof snow load?
Some snow is blown off the roof to the ground and some is melted by heat from the roof. In general, roof snow loads are somewhere between 50-90% of the ground snow load, depending on the exposure and heat transfer. Calculate unbalanced snow loads caused by sliding or drifting snow.
What is snow load rating?
Snow load is the load, in pounds per square foot, placed on the exterior of a structure by snow accumulation. The snow load capacity for each structure must be determined on a case-by-case basis and is determined by the building materials used and the style of construction, as well as roof surface area.
Is snow a dead load?
Live loads are temporary loads; they are applied to the structure on and off over the life of the structure. The most common types of live loads are occupancy (floor) load, workers during construction and maintenance, snow, wind and seismic.

What is a ground snow load?
A snow load is the burden placed on the ground or on a structure by snow, rime , and ice that has accumulated. Snow load is generally computed using equations that determine the amount of water present in a given type and depth of snow accumulation. The ground snow load is computed first, based on an average sample…
