Hello,
I assume you have already read Troubleshooting, 2.2.5 How to model bonded post-tensioning cables in ATENA?, and therefore I need to ask you to send us your model etc (Troubleshooting, 2.1.1) such that we can help you identifying the problem source.
Regards.

Also i gave the deviator very small coefficient of friction to neglect it's effect on the cable

Is this a reason for slippage of the cable at deviator points ?

Hi all ,

Please i want to model unbonded post-tensioning cables but i can't ... the main problem is the slippage of cable in deviator points .

My question is how can i overcome slipping of cable at the deviator points ,,, which are the points where the cable direction changes ?

I modeled the deviator as steel plate and the cable passes through it but it always gives me slippage ????
