Pole Wind Load Calculator



Poles and similar vertical structures are vulnerable to wind forces that can potentially compromise their structural integrity. To ensure the safety and longevity of these structures, engineers and designers must accurately assess the wind loads they will encounter during their lifespan. The Pole Wind Load Calculator is a crucial instrument in this endeavor, providing a systematic approach to calculate the wind-induced forces.


The Pole Wind Load Calculator relies on a fundamental formula for calculating wind loads:

Wind Load (WL) = 0.5 x ρ x V² x A x Cd


  • WL is the wind load in pounds or newtons.
  • ρ (rho) is the air density in pounds per cubic foot or kilograms per cubic meter.
  • V is the wind speed in miles per hour or meters per second.
  • A is the projected area of the pole or surface exposed to the wind in square feet or square meters.
  • Cd is the drag coefficient, which is dimensionless and varies depending on the shape of the pole.

How to Use?

Using the Pole Wind Load Calculator involves several key steps:

  1. Gather Information: Collect the necessary data, including the wind speed (V), air density (ρ), projected area (A), and the drag coefficient (Cd) of the pole or structure in question.
  2. Apply the Formula: Plug these values into the formula: Wind Load (WL) = 0.5 x ρ x V² x A x Cd.
  3. Calculate: Utilize the calculator to compute the wind load, which represents the force exerted by the wind on the pole.
  4. Evaluate Results: Analyze the calculated wind load to determine whether the pole or structure can withstand the applied forces, considering safety factors and design specifications.


Let’s illustrate the use of the Pole Wind Load Calculator with an example:

Suppose you have a flagpole with a projected area (A) of 1.5 square meters, a wind speed (V) of 25 meters per second, an air density (ρ) of 1.225 kilograms per cubic meter, and a drag coefficient (Cd) of 0.7. Using the formula:

Wind Load (WL) = 0.5 x 1.225 kg/m³ x (25 m/s)² x 1.5 m² x 0.7

Calculating this, we get:

WL = 1078.125 N (newtons)

So, the wind load on the flagpole is approximately 1078.125 newtons.
