Estimating wind loads on banners

Wind loads on banners can be estimated and a simple example is shown below. A 90 mph, (40m/s) three second gust has a basic wind pressure of 15 psf (720 pascal or 0.72kN/m2). Codes adjust this with a coefficient of pressure and for a square fabric sign is a minimum of Cp = 1.45. For …
