RelConnectsStructuralMember

Hinges on 1D member

The entity RelConnectsStructuralMember allows users to release degrees of freedom between structural members (beams, columns) and structural connection objects (nodes or supports). When no RelConnectsStrucutralMember is defined, connections are taken into account as fully rigid. The defined connections may be rigid or free or anything in between. In each direction (translations along X, Y, and Z local 1D member axes, rotation around X, Y, and Z local 1D member axes) the condition may be: Free, Rigid, Flexible.

ux
Enum
Free
Rigid
Flexible
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.
uy
Enum
Free
Rigid
Flexible
yes
Translation in Y 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.
uz
Enum
Free
Rigid
Flexible
yes
Translation in Z 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.

fiz
Enum
Free
Rigid
Flexible
yes
Rotational stiffness around Z axis. Parameter Flexible can be linear only, non-linearity is not supported.
Stiffness X [MN/m]
Double
100
yes, if ux = Flexible
The flexibility of the connection in X direction
Stiffness Y [MN/m]
Double
100
yes, if uy = Flexible
The flexibility of the connection in Y direction
Stiffness Z [MN/m]
Double
100
yes, if uz = Flexible
The flexibility of the connection in Z direction
Stiffness Fix [MNm/rad]
Double
50
yes, if fix = Flexible
The flexibility in rotation of the connection around local X axis
Stiffness Fiy [MNm/rad]
Double
50
yes, if fiy = Flexible
The flexibility in rotation of the connection around local Y axis
Stiffness Fiz [MNm/rad]
Double
50
yes, if fiz = Flexible

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.
Id
String
39f238a5-01d0-45cf-a2eb-958170fd4f39
no
Unique attribute designation

Notes

Hinge position is used for allowing users to define where degrees of freedom are released (user defined constrains).
When the fully rigid connection is desired - no RelConnectsStructuralMember is defined!
