BS EN 1990 Eurocode 'Basis of structural design', categorises loads, imposed deformations and accelerations as ‘actions’. It defines three types of action, distinguished by their tendency to change over time:
- Permanent actions (sometimes referred to as dead loads) are those actions that do not change over time, for example, self weight.
- Variable actions (sometimes referred to as live loads) are those actions that can change over time, for example, occupant loads, furniture loads, snow and wind loads.
- Accidental actions are the result of exceptional conditions, for example, fire or explosion.
