I'm not sure if I'm just unaware of a better method, but when models include expansion joints I find myself having to take the displacement report and putting them in an Excel sheet to calculate the deflections by direction for each case.

Is there an easier or pre-built method in the reports to do this? Or do most people just use the maximums for each direction and call it good?

It would be nice if there were an expansion joint report that pulled the specified stiffness data and then summarized the joint deflections in a nice report without additional work/input.
