Releases

Defines which releases are used for a rigid link start or end.

The options are:

• Automatic releases (by rules)

• User-defined releases

Start or End

Defines which of the predefined or user-defined combinations for releases is used for a rigid link start or end.

These are the predefined options:

These options automatically set the degrees of freedom.

You can modify a predefined combination to suit your needs. If you do that, Tekla Structures indicates it with this option:

Ux

Uy

Uz

Define the translational degrees of freedom (displacements) in the global x, y, and z directions.

The options are:

• Free

• Fixed

• Spring

If you select Spring, enter the translational spring constant. The units depend on the settings in File menu > Settings > Options > Units and decimals.

Rx

Ry

Rz

Define the rotational degrees of freedom (rotations) in the global x, y, and z directions.

The options are:

• Pinned

• Fixed

• Spring

• Partial release

If you select Spring, enter the rotational spring constant. The units depend on the settings in File menu > Settings > Options > Units and decimals.

Use Partial release to specify if the degree of connectivity is between fixed and pinned. Enter a value between 0 (fixed) and 1 (pinned).

Local Y direction

Defines the local y direction of the rigid link. The options are the global x, y, and z directions.

The local x direction is always the direction of the rigid link.
