The wind speed calculation for a light pole depends on several factors, including the pole’s height, diameter, and exposure to wind:

1. Determine the basic wind speed in the area where the light pole is located. This is typically expressed as a speed in miles per hour (mph) or meters per second (m/s). You can find wind speed maps and charts from local meteorological agencies or online sources

2. Calculate the wind pressure on the light pole. This is based on the pole’s exposure to wind, which is typically classified as either “exposed,” “partially exposed,” or “sheltered.”

3. Calculate the surface area of the light pole that is exposed to wind. This involves measuring the diameter of the pole and using this to calculate the cross-sectional area.

4. Use the wind pressure and surface area to calculate the force applied to the light pole by the wind. This is typically expressed in pounds per square foot (PSF) or Newtons per square meter (N/m^2). 5. Determine the pole’s design wind speed or ultimate wind speed.

This is the maximum wind speed that the light pole is designed to withstand without failing, and is typically expressed in mph or m/s. It’s important to note that wind speed calculation for light poles can be complex and is usually done by experienced engineers to ensure the poles are safe and secure.
