Applying prestressing load for 3D reinforcement

Post by zaherkurdi »

Dear,

I am writing to seek guidance on applying prestressing load on a 3D cylinder of steel in my model. Specifically, I have embedded reinforcement within a concrete cylinder, with the reinforcement created as a 3D cylinder and defined as solid steel (Steel VonMises 3D) and the concrete cylinder defined as solid concrete (Cementitious2). I have set a (constraint for surface) condition at the cut surface in the longitudinal direction and a (fixed contact for surface) condition between the reinforcement and the concrete.


To apply the prestressing load, I used (initial strain for volume) and applied the strain in the longitudinal direction. However, it appears that my approach did not work well. I have attached the GiD file for your reference.

Could you please provide instructions on how to correctly apply a prestressing force on a 3D cylinder of steel? Any guidance or insights would be greatly appreciated.

Thank you for your time and assistance.
Used software version: GiD 16.1.3d, Problem type: ATENA - GiD Build 18016 & ATENA 5.6.1.

Best regards,

Sorry, but this question must be asked to Atena developers, not to us (GiD).
We don't know what is doing the Atena solver with your input data.

Thank you for your response. I understand and appreciate your suggestion to contact the Atena developers directly.

Was the 3D cylinder representing the steel reinforcement accurately defined within your model? If you're still experiencing issues, I suggest reaching out to the Atena developers directly. I faced a similar problem and they were able to assist me within 48 hours. Well, actually earlier, because I contacted them on Saturday evening, and on Monday morning, I already received an answer.
