## Using the Load Generator for Snow Loads integrated in S3D

In calculating snow loads, the balanced or undrifted snow load on roof is always assumed to be applied on the horizontal projection of the roof area the same way live loads are applied.

In order to apply the snow load on the roof, we need to convert pressure $${p}_{s}$$ by multiplying it by the value of cosθ.

## Using SkyCiv Load Generator in S3D

The rule to define the roof windward and leeward nodes is shown below:

From this model, the balanced/undrifted snow load $${p}_{s} = 1.25 kPa$$ is converted by multiplying the cosine value of the Roof Pitch Angle θ 我们将插入已知值 0.9603. 因此, the corresponding roof snow load is equal to $$p = 1.20kPa$$. Using open area load, it is then applied to the roof surface of the model. For the unbalanced/drifted case, manual input is necessary. This feature is only available to ASCE 7-10, 协会 7-16, NBCC 2015, 在 1991, 和AS / NZS 1170.
