(+) and (-) signs signify wind pressures acting toward & away from respective surfaces. <br /> 2. Width of Zone 2 (edge), 'a' = 3.00 ft. <br /> 3. Width of Zone 3 (corner), 'a'= 3.00 ft. <br /> 4. For monoslope roofs with 0 <= 3 degrees, use Fig. 30.4-2A for'GCp'values with 'qh'. <br /> 5. For buildings with h > 60' and 0 > 10 degrees, use Fig. 30.6-1 for'GCpi'values with 'qh'. <br /> 6. For all buildings with overhangs, use Fig. 30.4-26 for'GCp'values per Sect. 30.10. <br /> 7. If a parapet>= 3' in height is provided around perimeter of roof with 0 <= 10 degrees, <br /> Zone 3 shall be treated as Zone 2. <br /> 8. Per Code Section 30.2.2, the minimum wind load for C&C shall not be less than 16 psf. <br /> 9. Reference: a. ASCE 7-10, "Minimum Design Loads for Buildings and Other Structures". <br /> b.
