Wind load on canopies
Wind load on canopies
(OP)
Does anyone know of any literature that addresses wind load on canopies? I have been designing canopies for eave loading, but I honestly don't think eave loading is appropriate. Eave loading involves continuous air flow on top with little airflow below. This would certainly require significant overall upward pressure due to Bernoulli's principle. But I don't see that affect happening at canopies. In fact, for low canopies on tall buildings, I don't see why airflow would be any different between above and below the canopy.

Be conservative, be very conservative.

The canopies were beautiful and effective when new.
Hurricane Wilma stripped off all the fabric but left the sturdy cables.
Repairs still not quite complete.

Check out CP3 and BS6399
Both give clear guidance, and allow you to calculate wind loads depending on whether the canopy is fully open below, is blocked below, or partially open
Failing that, and for simple small canopies only, I have sometimes calculated the wind pressure as if it were a roof, and then factored by 2.
