Signs with openings making up 30% or more of the gross area are classified as open signs. <br /> 2. Calculation of the design wind forces shall be based on the area of all exposed members and elements projected on a plane normal <br /> to the wind direction.Forces shall be assumed to act parallel to the wind direction. <br /> 3. Area A f consistent with these force coefficients is the solid area projected normal to the wind direction. <br /> ASCE 7-16 Table 29.4-2 <br /> D:=1 ft approximate depth of purlin and roof decking <br /> £ _ D•B+h•(6 in) =0.153 <br /> h•B <br /> Cf:=1.8 per Table 29.4-2 <br /> Pf:=max(qh•G•Cf,16 ps�=17.86 psf (29.4-2) <br />
