Define end releases and support conditions

In structural analysis, the stresses and deflections of a part depend on how it is supported by, or connected to, other parts. You normally use restraints or springs to model connections. These determine how analysis parts move, deflect, warp, and deform in relation to each other, or to nodes.

Part ends and nodes have degrees of freedom (DOF) in three directions. The displacement of a part end can be free or fixed, and the rotation can be pinned or fixed. If the degree of connectivity is between free, or pinned, and fixed, use springs with different elastic constants to model them.

Tekla Structures uses analysis part, connection, or detail properties to determine how to connect parts in the analysis model.

The analysis part properties determine the degrees of freedom for each end of a part. The first end of a part has a yellow handle, the second end has a magenta handle.
