Design Wind Pressure for Signs q h = wind pressure at top of sign G = wind gust coefficient A s = area of the face of sign C f = force coefficient affected by sign dimension and clear area ratio (for B/s = 4 see table 1-6). B=width of sign & s=height of sign & h=elevation from ground to top of sign. F = q h GC f A s
Snow Load Parameter that affects snow load: Roof geometry, Wind exposure, Location, Importance, Heated structure or not For roof slope < 5% then multiply snow load (p g ) by the following factors: p f = 0.7C e .C t .I.p g Where: C e = 0.8 in an unobstructed area & 1.2 if sheltered in a large city. C t = 1.2 for unheated structures & 1.0 for heated structures I = 0.8 for agriculture and storage facilities & 1.2 for hospitals Conditions: if p g ≤ 0.96 kN/m 2 then use the larger of p f = 0.7C e .C t .I.p g or p f = I.p g If p g > 0.96 kN/m 2 then use pf = I. 0.96 kN/m 2
