Description:
Snow load - Duopitch roof
Annotation:
Characteristic value of snow load on the ground and Coefficients
These parts of calculation are described in the annotation for
Coefficients for the snow load
Geometry
Left and
right
slope
is
drawn here in degrees.
Left and right side shape coefficients are calculated.
Angle of pitch of roof α
0° ≤ α ≤ 30°
30° ≤ α ≤ 60°
α ≥ 60°

Calculation of the snow load
Case (i) -
Undrifted
snow
Snow loads s
1
and s
2
are calculated
according
formula (5.1) in kN/m
2
Case (ii) and Case (iii) -
Undrifted
snow
Shape in these cases
depend
on selected national annex.
Standard shapes are calculated
according
formula (5.1) with proper coefficient μ
i
Explanation of symbols
s
1
- Snow load on the left side of the roof [kN/m

]
s
2
- Snow load on the right side of the roof [kN/m
2
]
α
1
- Roof slope on the left side of the roof [°]
α
2
- Roof slope on the right side of the roof [°]
μ
1(α1)
- Shape coefficient on the left side of the roof
μ
1(α2)
- Shape coefficient on the right side of the roof
