Unbonded Post-Tensioning
Unbonded Post-Tensioning
(OP)
Here's a dumb question:
In any unbonded post-tensioned system, what is the actual physical mechanism that engages the tendons for the purposes an ultimate strength check?
In the ultimate strength check, we assume the tendons are stressed to yield, but what physical mechanism engages the tendons to increase their stress beyond the initial prestess if there is no strain compatibility between the concrete and the tendons?

Michael.
Timing has a lot to do with the outcome of a rain dance.

otherwise, when the flexural member is experiencing moment, the tendons will contribute as Atendon*fpe.
