CSM Cable prestress

Dear all,

I am working on my thesis, which is a cable-stayed bridge. The estimated formfinding runs correctly, however, the first form finding iteration removes the prestress from one of my cables and that cable group won’t get stress anymore. What could be causing this?

Thank you in advance,
Király Nándor

Hello Király,
the problem you described concerns the ropes of group 200. And this is understandable because this group does not receive any pretension: In task “Formfinding final System” pretension is only applied to groups 201-216.

Best regards,
