snow load 1

Here's an ASCE-7 snow load calculator.

This is an online version of what's in the code. This site could be more accurate with feedback regarding local requirements and known ammendments.

Snow? I've heard of that stuff but never seen it.

The density of snow that you recommend sounds extremely light!

Snow density to be used in calculating for drifting (per ASCE 7) = 0.13 Pg + 14 but not to exceed 30 pcf.

I have read that snow density often varies between 15 to 30 pcf. In fact, when a number of buildings (all pre-engineered) collapsed in our state in the winter of 1979 - 1980, I measured the snow on one of them and it was at 55 psf for 2 feet of snow, which was 27.5 pcf! The buildings were designed for LL = 30 psf.

We routinely see buildings that need to be designed for well over 100-110 psf for snow drift conditions. We use 19 pcf for snow density in this equation.

"Nice tool, thanks!"

No problem.

Any info. on local ground snow requirements in case study areas would be much appreciated.
