|Auflagerreaktion / Schnittkraft (allgemein)|
A structural reaction is a structural activity that results from a
structural action imposed to a structural item or building element. Examples are support reactions,
internal forces, and deflections.
HISTORY New entity in IFC2x2.
IFC4 CHANGE Inverse attribute Causes deleted; use IfcRelAssignsToProduct via HasAssignments instead.
Structural reactions are grouped into IfcStructuralResultGroups via the inverse
relationship HasAssignments and an IfcRelAssignsToGroup relationship object.
IfcStructuralResultGroup.ResultGroupFor finally refers to the structural analysis model
in which the results occur.
It is furthermore possible to establish relationships between reactions in one analysis model
and actions which they cause in another analysis model. 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 HasAssignments of the reaction and an
IfcRelAssignsToProduct relationship object. IfcRelAssignsToProduct.Name is set to
'Causes' and IfcRelAssignsToProduct.RelatingProduct refers to an instance of a subtype of
