(+) and (-) signs signify wind pressures acting toward & away from respective surfaces. <br />2. Width of Zone 2 (edge), 'a' =3.40 ft. <br />3. Width of Zone 3 (corner), 'a' =3.40 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. 30.4-2B 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. References : a. ASCE 7-02, "Minimum Design Loads for Buildings and Other Structures". <br />b.
