RE: Modeling of pot bearings in SEISAB
As for translation there are two types: those that allow translation and those that don't. When translation is accomodated it is usually with a tongue and groove PTFE/mirror interface. The only constraint here is the frictional force. Once you overcome that, it moves and the restraint is removed - which makes this analysis an iterative one. Frictional values for PTFE surfaces can be found in AASHTO or other bearing references.
