Design wind loads for a low-rise building taking into account directional effects

The basic idea of a directional design is to optimize the orientation of a building, e.g. to have the strong axis in the strong wind direction and to have the weak axis in the direction of the weaker storms. However, it has to be understood that the wind load depends on two key random variables: the extreme wind speeds and the extremes of the wind-induced actions or action effects. Generally, the complex interaction of the corresponding directionalities does not allow separating the two variables. A consistent analysis is presented on the example of a low-rise building.
