Glossary Term

In structural engineering, an action describes a force or deformation acting on a structure.

Action Types

Actions are divided into permanent and variable actions. Permanent actions include dead load, floor structure, roof structure, and others. Wind, snow and live loads represent variable actions. For example, wind loads usually have a favorable effect on a supporting structure, since they are generally lifting loads. Therefore, actions are further divided into actions with favorable and unfavorable effects.

Entering in RFEM/RSTAB

In RFEM/RSTAB, actions are assigned to each load case in action categories. In this case, the actions are classified according to the respective standard.
