Probably a simple question here! Can someone walk me through the proper inputs on a restraint?

Example support criterea: A pipe sitting on top of a very tall T-pole. There's no guides or axial stops. The friction of the pipe shoe is the only horizontal loads acting on the T-pole.

In order to more accurately determine loads at the support, I want to include the stiffness of the T-pole, which I can get from my Structural Engineer. At this support location in my model:
-What are the exact restraint types (ie +y, x, z, etc)
-Which do you apply friction to if any
-Which do you apply stiffness values of the T-pole to?

Thanks!
