are calculated using Section 6.5.7 and Figure 6-4 based on the shape and steepness of the terrain features. If no significant topographic features exist, Step 5: Determine the Wind Directionality Factor ( Kdcap K sub d

This is the 3-second gust speed at 33 feet above ground in open terrain. It is found on the wind speed maps (Figures 6-1 through 6-4 in ASCE 7-05). wind load calculation as per asce 7-05

(Internal Pressure Coefficient): Varies based on building enclosure (Enclosed: ±0.18plus or minus 0.18 , Partially Enclosed: ±0.55plus or minus 0.55 ).
