Snow Loads. The snow loads specified in Table R301.2(5b) shall be used for the jurisdictions
identified in that table. Otherwise, the ground snow load, Pg, to be used in the determination
of design snow loads for buildings and other structures shall be determined by using the
following formula: Pg = (Po2 + S2(A-Ao)2)0.5 for A greater than Ao, and Pg = Po for A less
than or equal to Ao.
WHERE:
Pg = Ground snow load at a given elevation (psf);
Po = Base ground snow load (psf) from Table No. R301.2(5a);
S = Change in ground snow load with elevation (psf/100 ft.) From Table No. R301.2(5a);
A = Elevation above sea level at the site (ft./1,000);
Ao = Base ground snow elevation from Table R301.2(5a) (ft./1,000).
The building official may round the roof snow load to the nearest 5 psf. The ground snow
load, Pg, may be adjusted by the building official when a licensed engineer or architect submits
data substantiating the adjustments.
Where the minimum roof live load in accordance with Table R301.6 is greater than the design
roof snow load, such roof live load shall be used for design, however, it shall not be reduced to
a load lower than the design roof snow load. Drifting need not be considered for roof snow
loads less than 20 psf."
