Pipe stress and axial force

Hello everyone,

I have two questions about pipe stress and axial force in the model after interpretation the results from model.

I've attached the file to this post.

 

  1. Why is the force at A41 to A06 in the model the same? Should it be reduced because of friction of support? (GRTP case) Also, it happens on another side of the pipe (symmetric area) (point A07-A25)
  2. When I see the stress results (Rest+Function), the stress at every point is the same. I have doubt to this because I think the stress result at every point should be different due to axial force difference.case study 1.DAT
