Question:

If a snubber operates on both traction and compression, what is the difference between placing the + or - symbol or none when modeling it in Caesar II?

Thanks

center of rotation.

Yes, I would assume that such devices operate independent of direction so there would be no reason for a snubber to have +SNB or -SNB, the snubber would simply appear as SNB.
But there is another aspect of SNB that may be useful in CAESAR II modeling. These snubbers can be selectively activated or deactivated by load case. SNBs can be turned on or off in the load case editor for the basic load cases (not combinations). So if these SNBs are used to model translational restraints (e.g., +Y), that restraint could be included in one load case and excluded in another (maybe even identical) load case. Ergo, the sign. This allows the user to pose "what if" questions on modeling without having to build a second model or rerun a changed model. It's not really a snubber in this case but simply a CAESAR II manipulation.
