Maybe I could help if you explain more about your project.
If you intend to simulate unbonded post-tensioned concrete, microsimulation can be done by modeling each individual tendon with interaction with concrete and desirable characteristics.
post-tensioned for tendons can be performed in an initial step with the desired force applied by the hydraulic jack or in any other arbitrary manner. The loading can be applied in a static or dynamic approach.
about its end anchorage, it's necessary to explain more.
if you had any questions, give me a message or an email I'll be happy to help.
I have question how can I model the force for prestressing and end Anchorage for fu=270ksi strand with abaqus. If you have example or tutorial my email is
