Specified Snow Load
S = Is[Ss(CbCwCsCa)+Sr] [4.1.6.2]
Factors
User input values:
Ss = 1 / Sr = 1
Importance Factor, ULS: I
s = 1.0 / SLS: I
s = 0.9
Roof slope = 0 degrees
Slope Factor
For non-slippery roof:
Slope <= 30 degrees.
Cs = 1
ULS:
S = 1.0[1(0.8*1.0*1*1.0)+1] = 1.8kPa
S = 1.8 kPa
S = 37.6 psf
SLS:
S = 0.9[1(0.8*1.0*1*1.0)+1] = 1.62kPa
S = 1.62 kPa
S = 33.8 psf
