Loading
The load due to wind to be applied depends on the location, height, and shape of the structure to be designed.
The locations can be divided into wind load zones according to EN 1991‑1‑4. They can be found on maps such as these:
Snow Load, Wind Speed, and Seismic Load MapsThe wind load zones indicate the average wind speed in this area.
Then, depending on the geographical location of the structure (for example, inland areas or coastal areas), the peak velocity pressure qp(z) is determined.
You can the use the peak velocity pressure to determine the wind loads on the building. The flow direction and shape of the vertical walls or roof are especially crucial.
Load Application
The wind load is assumed to be perpendicular to the real length of a member, whereby there is pressure on the side facing the flow and suction on the opposite side.
