Snow Load on Open Louvers
Snow Load on Open Louvers
(OP)
I am analyzing a louver sunshade awning in a snow area with GSL of 40psf. Louvers have 40% solid, 60% open projection. Louver support is horizontal, louvers are slanted at 45 degrees to shade windows.
Need an opinion as to whether drift load should be applied to this.

I disagree with 3dboy for the following reasons:
1. Because the louvers are inclined at 45 degrees I would not expect significant accumulation at such a steep angle.
2.I assume that they are made of metal which would conduct solar heat and melt the snow and prevent any significant accumulation.
3. Louvers are aligned in a vertical plane. Depending on the spacing of the louvers, any given louver would be protected from large accumulations by the one above it.
4. Its overkill.

The openness in the code allows for assumptions and interpretations. We have a responsibility to follow the design codes, but we also are obligated not to follow them blindly.
