Modelling prestressed concrete / tendons in Karamba
Hi everybody,
I am trying to model a prestressed ruled surface shell with tendons in karamba, my first approach was defining the tendons as beams, prestressing them with initial strain and then adding them to the assembly. To avoid rigid body movement of the beams i fixed them to the shell body with "beam joint agent" but that didnt work for me.
Does anybody have experience with this, or is it even possible at the moment with karamba?
Regards,
Max

Hi Clemens,
thanks for your answer. I also wrote to the support and they send me a version pretty similar to what you wrote. But still I am getting an error message, that says that there are rigid body modes in the system and the shell isnt being calculated.
In the model I came up with, there is no error message about rigid body modes, however the shell is not being calculated or shown.
Im not looking for double support, but i think this topic of prestressed shell structures might be interesting for others. So if the support finds a working solution I'll post it here.
Regards,
Max
