Silo Wind Load Calculator


  • Cylindrical silo shape
  • Wind speed of 70 mph
  • Exposure Category C (Open terrain with scattered obstructions)
  • Silo diameter (D) in feet
  • Silo height (H) in feet
  • Area (A) in square feet
  • Wind Pressure (PSF) in pounds per square foot

Here’s a simplified table for estimating wind loads on a cylindrical silo:

Silo Diameter (D)Silo Height (H)Area (A)Wind Pressure (PSF)
10 feet30 feetCalculate based on formula
12 feet40 feetCalculate based on formula
15 feet50 feetCalculate based on formula
18 feet60 feetCalculate based on formula
20 feet70 feetCalculate based on formula

To calculate wind pressure (PSF) for each combination of diameter and height, you can use the formula:

Wind Pressure (PSF) = 0.00256 * Wind Speed (mph)² * Kz * Kzt * Kd * A


  • Wind Speed (mph) is the wind speed you want to consider (e.g., 70 mph).
  • Kz is the velocity pressure exposure coefficient (varies with height).
  • Kzt is the topographic factor (usually 1 for open terrain).
  • Kd is the wind directionality factor (usually 0.85 for not explicitly designed for wind loads in a particular direction).
  • A is the area of the silo’s projected face (π * (D/2)²).

Keep in mind that actual wind loads can vary based on local building codes, terrain, and other factors. It’s essential to consult with a structural engineer and follow applicable standards and codes for accurate calculations when designing a silo to withstand wind loads.
