ASCE 7-22 Door/Window Wind Pressure Calculator
Instructions
This calculator estimates wind pressures on doors and windows based on the ASCE 7-22 standard. Follow these steps:
- Risk Category: Select the category that best describes your building (e.g., Category II for standard residences).
- Wind Speed: Enter the wind speed in mph from ASCE 7-22 wind speed maps for your location and risk category.
- Building Dimensions: Enter the length, width, and height of your building in feet.
- Exposure Category: Choose the exposure category based on surrounding terrain (e.g., B for urban areas, C for open terrain).
- Effective Wind Area: Enter the area of the door or window in square feet.
Determining the Zone: If your door or window is within ‘a’ feet from the building’s corners, it is in Zone 5; otherwise, it is in Zone 4. The value of ‘a’ is calculated and displayed in the results.
Click “Calculate” to see the estimated wind pressures for Zone 4 and Zone 5.
