Applying prestressing load for 3D reinforcement
Posted: Wed May 10, 2023 4:13 pm
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,
