Given: 1. Wind direction is perpendicular to the roof ridge (see Figure 11-22). 2. Wind speed is 120 mph (3-sec peak gust). 3. DFE = 14 feet NGVD 4. Building is one-story: wall height - 10 feet. 5. Main roof pitch is 6:12. 6. Exposure is Category C (refer to ASCE 7-98). 7. The following values are determined from ASCE 7-98: Kg-0.85 K -0.93 (from interpolation of Table 6-5 in ASCE 7-98) K-1.0 G-0.878 (calculated using Equation 6-2 in ASCE 7-98) Mean roof height (h) -24.0 feet above ground Wind Loads Roof Line- Roof Ridge Porch Wind Direction Figure 11-22 Building elevation and plan view of root 8. The building is "enclosed." 9. The building is in a V zone within 1,600 feet of the shoreline. 1 of 1 Walls Plan View of the House Find: 1. design pressures for the MWFRS (including the porch roof): a) for wind perpendicular to the main roof ridge (east-west) b) for wind parallel to the main roof ridge (north-south) 2. design pressures for the components and cladding for an assumed effective area of 20 ft
