Wind Load on Slat Canopy
Wind Load on Slat Canopy
(OP)
I have a wood canopy over a large patio that is composed of 2x2 slats at 3 inches on center supported on 2x8's at 2' o.c. The intent is to create some shade over the patio. The horizontal projected area of the structure is essentially the 2x8 and 2x2 (about 10" nominally). However, since wind doesn't actually blow perfectly straight horizontally, I believe the actually lateral loading on the structure is a result of some wind pressure against each of the 2x8 rafters at some shallow angle, perhaps 10 degrees or so. I can't find anything in the codes that addresses this kind of situation. Any suggestions?

However it is in the standing code for loads on bridges that the wind forces on elements in the wind shadow of others is better defined. This code is

and the shadow thing in wind of course

Thanks for the response. Unfortunately, I don't speak spanish so the web sites aren't of much use. Also, would you mind explaining what "10 sexagesimal degrees" means? I looked up sexagesimal in the dictionary and it means 60.
