External Tendons

[neznajko]

I am getting strange behaviour of external tendons. If the tendon is completely inside a member everything seems to be OK. if the tendon is external - strange loss of prestress is occuring. (see attachment). Does anyone have an idea why this is happening and how to avoid it?

Thanks

This is a really strange situation, I never came across, to be honest..
