Dear Michaela,

thanks for your reply, but this is not what I'm trying to do.

I'm trying to simulate the structural behavior of prestressed beam under corrosion-induced tendon failure.

Therefore I want to break the prestressed tendon in half while the load is still constant.

Dear Chassan,
if you want to replace the material that is damaged for intact one, I would recommend to use exchange of material. The procedure is explained in manual for Construction process called "ATENA-Science-GiD_Tutorial_ConstructionProcess.pdf" which you can find in installed documents.

I hope this helps.

Intentionally damaging prestressed tendons

Hello everyone,

I apologize if this topic has been asked before, but I did not find an answer.

I'm currently researching the possibilities of replacing corrosion damaged prestressed tendons, and I'm having trouble while damaging the existing tendons.

How should I approach this issue? I already tried simply splitting the reinforcement lines and switching the material from bar with bond parameter Bar End: Fixed BOTH to Fixed NONE, but it didn't make a difference in simulation.

I'd really apreciate any kind of help, as I'm fairly new to using GiD Atena.

Thanks in advance,

Chassan Zin
