Control Displacement in a Restraints

[fabiogardenghi]

Is it possivel in the SAP2000 to fix a limit of displacement in a restraint?
For example:
I have a restraint that is defined: Translation 2 and 3 = Fixed / Translation 1 = Free.
But I want to limit the displacement in direction 1 in 20mm, because I have a mechanical stop.
Any one can help me?
Thanks.

Use a spring initially and iterate the analysis until you get 20mm translation.

Define a nonlinear link Gap or Hook, depending on whether it's compression or tension, with 20mm opening and run load case as a nonlinear analysis. Local direction of Link needs to correspond with joint local axis 1 (X) in your example. This problem requires a nonlinear analysis
