For Case A when GCpf is neg. in Zones 2/2E:For Case B when GCpf is neg. in Zones 2/2E: Zones 2/2E dist. =23.33 ft.Zones 2/2E dist. =23.33 ft. Remainder of roof Zones 2/2E extending to ridge line shall use roof Zones 3/3E pressure coefficients. MWFRS Wind Load for Load Case A, Torsional Case MWFRS Wind Load for Case B, Torsional Case Surface GCpf p = Net Pressure (psf) Surface GCpf p = Net Pressure (psf) (w/ +GCpi) (w/ -GCpi)(w/ +GCpi) (w/ -GCpi) Zone 1T --- 1.29 2.97 Zone 1T --- -2.94 -1.26 Zone 2T --- -4.06 -2.38 Zone 2T --- -4.06 -2.38 Zone 3T --- -2.79 -1.11 Zone 3T --- -2.57 -0.89 Zone 4T --- -2.48 -0.80 Zone 4T --- -2.94 -1.26 Zone 5T --- --- ---Zone 5T --- 1.03 2.71 Zone 6T --- --- ---Zone 6T --- -2.19 -0.51 Notes: 1. For Load Case A (Transverse), Load Case B (Longitudinal), and Torsional Cases: Zone 1 is windward wall for interior zone. Zone 1E is windward wall for end zone. Zone 2 is windward roof for interior zone. Zone 2E is windward roof for end zone. Zone 3 is leeward roof for interior zone.Zone 3E is leeward roof for end zone. Zone 4 is leeward wall for interior zone.Zone 4E is leeward wall for end zone. Zones 5 and 6 are sidewalls.Zone 5E & 6E is sidewalls for end zone. Zone 1T is windward wall for torsional case Zone 2T is windward roof for torsional case. Zone 3T is leeward roof for torsional case Zone 4T is leeward wall for torsional case. Zones 5T and 6T are sidewalls for torsional case. 2. (+) and (-) signs signify wind pressures acting toward & away from respective surfaces. 3. Building must be designed for all wind directions using the 8 load cases shown below. The load cases are applied to each building corner in turn as the reference corner. 4. Wind loads for torsional cases are 25% of respective transverse or longitudinal zone load values. Torsional loading shall apply to all 8 basic load cases applied at each reference corner. Exception: One-story buildings with "h" <= 30', buildings <= 2 stories framed with light frame construction, and buildings <=2 stories designed with flexible diaphragms need not be designed for torsional load cases. 5. Per Code Section 28.3.4, the minimum wind load for MWFRS shall not be less than 16 psf. 6
