Mon04loped roofs Include gables where the slope of the roof Is less than 1. In 12-. Notes: 1. Above spans do not include length of knee brace. Add horizontal distance from upright to center of brace to beam connection to the above spans for total beam spans. 2. For 140 MPH or higher wind zones, multiply spans by: 0.88 where deflection is applied ('d') or by 0.82 where bending is applied ('b') 3. Spans may be interpolated. Example: Rnd the maximum span for 2' x 4' x 0.045' Hollow Tilt Section for a load width of 5' and a 3 span over hang condition: a) for up to 120 MPH wind zone, the maximum span = 8'-4" 'b' b) for 140 MPH or higher wind zone. the maximum span = 8.33" 0,82 = 6.83' = 6'-10' Lawrence E.
