Static Wind Analysis


The static wind loads are the average or peak loads that act on a structure due to the mean wind speed and pressure distribution. Usually, just an Equivalent Static Wind Load will be created as a Load Case or as a Load Set, including a simple load defined by the applied forces.

The wind is included in the structural analysis as an additional load with the duration type as non-permanent. Wind loads are usually applied over the superstructure and the mesostructure: piers, masts, or pylons; but, they can also be applied on the live load to consider special cases when the traffic causes a much higher barrier to interrupt the airflow. 

The user needs to discretize the structure with some subdivision to account for the displacements, but those necessary for the bridge span are generally enough. Therefore, it is common to have the wind pressure loads defined as directly distributed loads (DL). Moreover, Uniform element wind loads could be created as input and can also be eccentric to the structure, or they should be dependable on the cross-section height or even on the CS shape.
