class Ifc4::IfcStructuralCurveReaction : public Ifc4::IfcStructuralReaction

Definition from IAI: Defines a reaction which occurs distributed over a curve. A curve reaction may be connected with a curve member or curve connection, or surface member or surface connection.

HISTORY: New entity in IFC 2x4.

Coordinate Systems:

See definitions at IfcStructuralActivity.

Topology Use Definitions:

Standard Case: If connected with a curve item, instances of IfcStructuralCurveRection shall not have an ObjectPlacement nor a Representation. It is implied that the placement and representation of the IfcStructuralActivity is the same as the ones of the member or connection.

Special Case: If connected with a surface item, instances of IfcStructuralCurveReaction shall have an ObjectPlacement and Representation, containing an IfcEdgeCurve. See IfcStructuralActivity for further definitions.

Informal propositions:

If the curve reaction is of the predefined type CONST, SELF\IfcStructuralActivity.AppliedLoad must not be of type IfcStructuralLoadConfiguration. If the curve reaction is of the predefined type LINEAR, SELF\IfcStructuralActivity.AppliedLoad shall be of type IfcStructuralLoadConfiguration and shall contain two items. If the curve reaction is of the predefined type POLYGONAL, SELF\IfcStructuralActivity.AppliedLoad shall be of type IfcStructuralLoadConfiguration and shall contain three or more items. If the curve action is of the predefined type DISCRETE, SELF\IfcStructuralActivity.AppliedLoad shall be of type IfcStructuralLoadConfiguration and shall contain two or more items. In case of types LINEAR, POLYGONAL, and DISCRETE, the load items shall have one-dimensional IfcStructuralLoadConfiguration.Locations, defining the location of the result samples in local coordinates of the curve reaction. The load items shall be provided in ascending order according to their locations. The first and the last load item define the extent of the result distribution. If the curve reaction is of the predefined type EQUIDISTANT, SELF\IfcStructuralActivity.AppliedLoad shall be of type IfcStructuralLoadConfiguration and shall contain two or more items. IfcStructuralLoadConfiguration.Locations shall be omitted as it is implicit. The load items shall be provided in ascending order. The first and the last load item are located at the beginning and end of the result distribution, respectively. All items in SELF\IfcStructuralActivity.AppliedLoad\IfcStructuralLoadConfiguration.Values shall be of the same entity type.
