Can someone please tell me how to caluclate the wind load for a sign that is going in at my Dad' office. I don't have a copy of the International Building Code, or ASCE 7.02.
The sign is 7' x 2', with 4 4"x6"'s that will hold up the sign in 2' concrete. The sign itself is 14 ft^2, and I came up with a total surface area with the posts of 22.1666 ft^2. I would be happy to email a spec sheet in pdf format to anyone that could help. I was going to just use 20 lb/ft^2 for a surface under 70 elevation but I wasn't sure if it would be correct. The total height is only 9'. Thanks,
Josh
