Consult the wind speed maps in of ASCE 7-05. These speeds represent 3-second gust speeds in miles per hour (mph) at 33 feet above ground in Exposure Category C. Step 2: Determine Occupancy Category
Open terrain with scattered obstructions (the default). Exposure D: Flat, unobstructed areas and water surfaces. Step 4: Calculate Velocity Pressure ( wind load calculation as per asce 7-05
When using ASCE 7-05, ensure you are using the appropriate load combination factors ( 1.6W1.6 cap W for LRFD or 1.0W1.0 cap W for ASD) associated with service-level wind speeds. Consult the wind speed maps in of ASCE 7-05
) , which accounts for the hazard to human life and the need for the building to remain functional after a storm. Step 3: Determine Exposure Category (A, B, C, or D) wind load calculation as per asce 7-05
