You can use the wind load calculator to calculate the wind force on any construction. With this wind load calculator, you can calculate the wind pressure exerted on a roof, a signpost, or a steel structure based on wind speed, ensuring that it is strong enough to endure the worst storm.
When humans build something, they must fight the environment to keep it standing. Roofs fall under the weight of snow, and floods and fire can erase your life's effort in seconds.
However, one of the most dangerous elements is one that we need to live in: air. Storms cost over $40 billion in damage and knocked off power to over 40 million people in 2019. Wind loads on rooftops that are too high cause structures to collapse and put people in danger. But don't worry; this wind force calculator can help you calculate the wind load on any structure based on wind speed and surface area. As a result, you can ensure that an unsteady roof, window, or sign does not endanger your family or property.
And, knowing that the wind will not harm you, you may use it to generate sustainable, clean, and inexpensive electricity with your own wind turbine. Use it for a fun activity like windsurfing or the more difficult kitesurfing.
The wind load on a structure is the force of air particles striking a surface. We'll need further info about the wind and the structure to compute the precise force:
Dynamic pressure is created when air molecules collide with an object, and it is determined by wind velocity and air density. Humidity, pressure, and temperature all affect air density. We use a default setting of 1.225 kg/m3 / 0.0765 psi in this calculator, which corresponds to a temperature of 15°C/59°F at sea level. Standard temperature and pressure describe these parameters (STP). If you live in an area with drastically different conditions, we suggest using the air density calculator to get your air density and then adjusting the value inside this calculator accordingly.
The effective surface area of your building also influences the wind load. The surface that is orthogonal to the wind direction is the effective surface. We can determine the effective surface by multiplying the total surface by the angle, assuming that the wind has always been parallel to the horizon. Even though the wind speed and surface area are equal, a surface at 90 degrees to the ground will experience significantly more wind stress than a 45° roof pitch.
The wind pressure calculator calculates the dynamic pressure and wind load by taking into account all of these variables:
Dynamic pressure = 0.5 * Air density * Wind speed²
Wind load = Dynamic pressure * Effective surface = Dynamic pressure * Total surface * sin(angle)

We'll show you how to utilise the wind load calculator in the following section.
1. What is the maximum weight that a 100 mph wind can lift?
At 100 mph, the pressure per square foot rises to 20 to 28 pounds, and at 130 mph, the pressure rises to 34 to 47 pounds per square foot.
2. Is there a wind load in code 875 Part 3?
Wind impacts on buildings and structures, as well as their components, are covered in this code. This Code does not apply to structures such as chimneys, transmission line towers, cooling towers, or bridges. There are various Indian Standards for chimneys and cooling towers.
3. How do you find out how much wind there is?
You may calculate the wind load using the formula force = area x pressure x Cd if you have pressure and drag data. For a 100-mph wind, the area – or length x breadth – of a flat piece of a structure could be set to 1 square foot, resulting in a wind load of 1 x 25.6 x 2 = 51.2 psf.
4. What is the formula for calculating wind force on a surface?
Air density times area equals the mass of air striking a surface. The wind speed in metres per second (m/s) is multiplied by the acceleration (a). Calculate the force in Newtons by using the formula force (F) = mass (m) times acceleration (a) (N).
5. How do you calculate wind load?
A wind load is a measurement of the wind's force on a surface, which can be expressed as a total force or as a pressure (which simply forces per unit area). Newtons or Pascals are the SI wind load units.
