Topic: 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

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.

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.
