- Define link properties through Define > Section Properties > Link/Support Properties.
- Set the Link/Support Type to Gap (Figure 1).
- Specify link properties under Directional Properties. Compression-only properties may be specified for each direction (Figure 1).
Set stiffness and open distance through Nonlinear > Modify/Show.
Figure 1 - Set stiffness and open distance
- Select the joint to which the link will be assigned, then model the link through Draw > Draw 1 Joint Link.
Please note that both links and springs are available for modeling, though links are more powerful because they enable nonlinear behavior and may be used either as supports or as connections between two non-grounded joints. Nonlinear link properties are only active when running a nonlinear load case.

TO DO: This should be re-written for line-spring assignments that may or may not use link properties. The fact that links are automatically generated for the analysis model at the |
