Hello,
I am trying to apply prestressing to strands in a concrete beam. The idea is:
1. I need to pull the strand by a force of 35 Kip (Loading Step).
2. Then cast the concrete and wait for 1 day so that the concrete beam is hardened enough.
3. After one day, the strands released by prestressed force transfer to the concrete beam (Unloading Steps).
I need to know the stresses, strains, and any cracking patterns after releasing the strands.
How I can assign BCs? Should BC be an initial step?
Should I need two steps for loading/pulling strands and unloading/Releasing of strands separately?
Anyone helps me to model all the above systems in ABAQUS?
Can anyone have files or models to share with me here?
