Hello, I have a quote for a tied-universal expansion joint and I want to model it in Caesar II. I have an over all length, bellows material, and axial and lateral spring rates for the TUEJ as a whole. For my model, I have a TUEJ generated by the EJ modeler.

If I understand things correctly, the springs rates I get from the CAESAR II EJ modeler are for each, individual, bellows element and not the TUEJ as a whole.

Assuming I am right in thinking I need to, how can I convert the spring rates given in quote to something I can use in Caesar II?

Also, any other tips for designing/verifying expansions joints with CAESAR II would be appreciated.

Thank you!
