Ground Snow equivalent depth?
Ground Snow equivalent depth?
(OP)
Need help here Please.
I have got a question on Snow load which puzzled me a long time.
In ASCE7-05, equation (7-3) gives the density of the snow:
Garma=0.13pg+14 but not more than 30pcf
according to this equation, one can calculate the equivalent depth of the snow covered on ground by divide the pg with above calculated Garma value, say if in a 40psf ground snow zone, the equivalent ground snow depth will be 40/(0.13*40+14)=2.08 ft. Is that conception correct?
Thanks.

Just wait till you have to design a wood roof to 400 psf and you are frantically trying to save the owner some money.
