Thank you for your reply. 

In this case, how are joints in ansys defined? In particular, what does a general joint which only allows translation in the x,y,z axis and no rotation mean? (How does Ansys calculate faces sliding over each other without defining coefficient of friction?) Also, is there anyway to add like a spring constant to a spherical joint in Ansys?

How would you recommend modelling a spherical bridge bearing?
