The Pole Wind Load Calculator is an invaluable tool used to determine the magnitude of wind forces acting upon poles. Its primary function involves computing the wind load exerted on a pole based on specific input variables. By inputting key parameters such as pole height, wind speed, and projected area, users can ascertain the potential wind load that the pole might endure.
Formula of Pole Wind Load Calculator
The calculation performed by the Pole Wind Load Calculator follows a formulaic approach:
F = 0.00256 * Kz * Kzt * Kd * V^2 * A
Where:
- F represents the wind load on the pole, measured in pounds or newtons.
- Kz denotes the velocity pressure exposure coefficient based on the pole's height above the ground.
- Kzt signifies the topographic factor, accounting for local terrain conditions.
- Kd indicates the drag coefficient, contingent upon the pole's shape (e.g., cylindrical or square).
- V denotes the wind speed at the pole's height, measured in miles per hour or meters per second.
- A represents the effective projected area of the pole perpendicular to the wind direction, measured in square feet or square meters.

Example of Pole Wind Load Calculator
Let's consider a scenario to illustrate the practical application of the Calculator. Suppose a cylindrical pole with a height of 10 meters, exposed to a wind speed of 20 meters per second, and a projected area of 5 square meters. Using the calculator formula, the wind load exerted on the pole would be calculated step-by-step.
Most Common FAQs
Answer: The projected area determines the surface exposed to the wind, influencing the force exerted on the pole. It's crucial for accurate wind load calculations.
Answer: Wind speed can vary at different heights. Typically, an anemometer is placed at the desired height to measure the specific wind speed.
