Ground Snow Load given Roof Snow Load Solution

STEP 0: Pre-Calculation Summary
Formula Used
Ground Snow Load = Roof Snow Load/(0.7*Wind Exposure Factor*Thermal Effects Factor*Importance Factor for End Use)
Pg = Pf/(0.7*Ce*Ct*I)
This formula uses 5 Variables
Variables Used
Ground Snow Load - (Measured in Pascal) - Ground Snow Load is used in the determination of the design roof snow load of a site.
Roof Snow Load - (Measured in Pascal) - Roof Snow Load is the downward force on a building's roof by the weight of accumulated snow and ice.
Wind Exposure Factor - Wind Exposure Factor is the factor of effect on exposure to wind.
Thermal Effects Factor - The thermal Effects Factor is the measure of the effect of exposure to heat.
Importance Factor for End Use - Importance Factor for End Use is the factor whose value lies in range 0.8 to 1.2.
STEP 1: Convert Input(s) to Base Unit
Roof Snow Load: 12 Pounds per Square Foot --> 574.563107758693 Pascal (Check conversion here)
Wind Exposure Factor: 0.8 --> No Conversion Required
Thermal Effects Factor: 1.21 --> No Conversion Required
Importance Factor for End Use: 0.8 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Pg = Pf/(0.7*Ce*Ct*I) --> 574.563107758693/(0.7*0.8*1.21*0.8)
Evaluating ... ...
Pg = 1059.92308839783
STEP 3: Convert Result to Output's Unit
1059.92308839783 Pascal -->22.1369539551358 Pounds per Square Foot (Check conversion here)
FINAL ANSWER
22.1369539551358 22.13695 Pounds per Square Foot <-- Ground Snow Load
(Calculation completed in 00.004 seconds)
