PT Stressing Sequence

[Yousef ZAA]

Is there any rule of thumb for stressing sequence? Additional reference to your recommendations would be appreciated.
And does it defers in case of pretensioning?

 

[Ingenuity]

Are you talking about suspended PT slab/beam systems in buildings and what elements should be stressed first/second etc., or whether to start stressing in the middle of slab and work towards the edges?

I think you mean 'differs in the case of pretensioning' - and yes, always POST-tension AFTER you PRE-tension

Give us some more info so we can better assist.

And is it bonded or unbonded PT? How much reinforcement has been supplied in the member? Is it a transfer member?

RE Pretensioning,it would be the release sequence that matters. Stressing sequence does not impart any stresses on the concrete.
