Dan Edgar,

Thank you very mich for your reply.

However, I do not see what is the best modeling ...

From what I understand, if the detailed method is used, it should not return values ​​of stiffness?

I looked in the application guide to modeling my expansion joint but I confess I am lost ...

According to you, what should I change my model for the expansion joint is correct?

Would you a model. CAESAR II with the two models?

Thank you in advance

Regards
