Consult the ASCE 7-05 wind maps. Unlike newer versions that use "Ultimate" speeds, ASCE 7-05 uses (3-second gusts). Typical values range from 85 mph in the interior U.S. to 150+ mph in hurricane-prone coastal regions. Step B: Find the Velocity Pressure (

For rigid buildings of all heights, the design wind pressure ( ) for MWFRS surfaces is calculated using:

The structural system that supports the entire building (e.g., frames, shear walls).

Windward walls contain significant openings that can pressurize the interior. Open Buildings: Each wall is at least 80% open. Exposure Category (B, C, or D)

External pressure coefficients represent the aerodynamic pressure variation across different surfaces of the building. Find these values in : Windward Wall: (constant for all heights). Leeward Wall: Cpcap C sub p varies based on the
