Snow Drift on Fabric Awnings
Snow Drift on Fabric Awnings
(OP)
Is there an appropriate time to neglect snow drift on a fabric awning? I'm looking at an aluminum frame supporting a fabric awning attached to the side of a restaurant. Per the code, there is a 42 psf snow drift (10psf ground). I don't really believe the fabric awning can support this load and so I'm left wondering if the frame should be designed for it.
Thanks.
Thanks.

nd don't forget to mix in the fabric degredation due to UV exposure over time.

You should make sure that the fabric portion of the design is clearly out of your scope, or analyze it properly.

For unobstructed slippery slopes greater than 15 degrees, the slope factor is (60 - alpha)/45.

Is your awning of a size where retraction is an option? The restaurant might save a few bucks on their heating bill as an added benefit.

Most small fabric structures that I have seen were not designed correctly.
Although sometimes they are designed based on the failure of the fabric rather than full loads.
