StructuralCurveConnection

Supports on 1D members

Object definition for a line support on a 1D member (StructuralCurveMember) or on a rib (StructuralCurveMemberRib). The support can be defined along the entire length of an edge or on its part only. This support is defined by six independent parameters. Each parameter defines the constraint in one direction: translation in X, Y, Z axis and rotation around the same axes. The parameters are the same as for line support on 2D memeber edge support (StructuralEdgeConnection).

Enum

Free

Rigid

Flexible

Compression only

Tension only

yes

Translation in X direction.

Free - That is it imposes no constraint in the direction. Rigid - The connection in fully rigid in the specified direction. Flexible - The connection is flexible (elastic) in the specified direction. Parameter Flexible can be linear only, non-linearity is not supported. Compression only acts only under compression. If the support gets under tension it stops acting. Tension only support acts only under tension.

yes, if Translation Z = Flexible

The flexibility of the connection in Z direction. Use this property only if the Translation Z direction is Flexible.

Stiffness Fix [MNm/rad/m]

Double

50

yes, if Rx = Flexible

The flexibility in rotation of the connection around local X axis. Use this property only if the Rotational stiffness Rx is Flexible.

Stiffness Fiy [MNm/rad/m]

Double

50

yes, if Ry = Flexible

The flexibility in rotation of the connection around local Y axis. Use this property only if the Rotational stiffness Ry is Flexible.

Stiffness Fiz [MNm/rad/m]

Double

50

yes, if Rz = Flexible

The flexibility in rotation of the connection around local Z axis. Use this property only if the Rotational stiffness Rz is Flexible.

Coordinate system

Enum

Global

Local

yes

Defines the co-ordinate system of the member in which the support is applied

Coordinate definition

Enum

Absolute

Relative

yes

Selects the coordinate system that is used to define the length of the support. Relative means without units. For define length of the hinges in meters input absolute

Origin

Enum

From start

From end

yes

Specifies the origin of the coordinate system used for the definition of the length of the hinge

Start point [m]

Double

value in meters for Coordinate definition = Absolute

0,0

value in percentage for Coordinate definition = Relative

0,0

yes

Defines the position of the start point of the support in relative or absolute coordinates [m]

End point [m]

Double

value in meters for Coordinate definition = Absolute

5,25

value in percentage for Coordinate definition = Relative

1,0

yes

Defines the position of the end point of the support in relative or absolute coordinates [m]

Parent ID

String

67b35d84-3d04-47aa-aa4a-dc1263982320

no

Is filled for objects created be dividing curved geometry to series of straight line objects. Parent ID will ensure that curved edge is imported as straight parts to nonsupporting application, and back to original supporting application as curved geometry.

To ensure successful round trip of segmented objects and their related objects, Parent ID needs to be present in both directions.
