Specified Snow Load

S = Is[Ss(CbCwCsCa)+Sr] [4.1.6.2]

Factors

User input values:
Ss = 1 / Sr = 1
Importance Factor, ULS: Is = 1.0 / SLS: Is = 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
