class Ifc4x1::IfcStructuralAction : public Ifc4x1::IfcStructuralActivity

Definition from IAI: A structural action is a structural activity that acts upon a structural item or building element.

HISTORY New entity in IFC 2x2. IFC 2x4 change: Attribute DestabilizingLoad made optional. Attribute CausedBy deleted; use IfcRelAssignsToProduct via ReferencedBy instead.

Structural actions are grouped into either an IfcStructuralLoadGroup of predefined type LOAD_GROUP or, more often, an IfcStructuralLoadCase. This is accomplished via the inverse relationship HasAssignments and an IfcRelAssignsToGroup relationship object. IfcStructuralLoadGroup.LoadGroupFor or IfcStructuralLoadCase.LoadGroupFor respectively refers to the structural analysis model(s) in which the loads are used.

It is furthermore possible to establish relationships between actions in one analysis model and reactions in another analysis model which cause the actions. For example, a support reaction from one structural system may be taken over as a load onto another supporting structural system. This is expressed by means of the inverse relationship ReferencedBy of the action and an IfcRelAssignsToProduct relationship object. IfcRelAssignsToProduct.Name is set to ‘Causes’ and IfcRelAssignsToProduct.RelatedObjects refers to an instance of a subtype of IfcStructuralReaction.

Public Functions

bool hasDestabilizingLoad() const

Whether the optional attribute DestabilizingLoad is defined for this IfcStructuralAction.

bool DestabilizingLoad() const

Indicates if this action may cause a stability problem. If it is ‘FALSE’, no further investigations regarding stability problems are necessary.
