Dear elham_ho64, unbonded cables are typically modelled as "external cables".

Which preprocessor are you using - ATENA Engineering 3D, or GiD? In ATENA 3D, spirals have to be approximated with multiple linear segmments, in GiD this approximation is done at the time of meshing - just apply a reasonable number of divisions to the curve representing the spiral reinforcement.

in this model I have described, i have post tensioned unbonded tendons
now i should define these tendons as external cables,or reinforcement bars?

Dear sir

I have a model of a precast post tensioned concrete shear wall
but i cant define spiral
i read the manual and did not find a note about this
Could you please explain me how to do this

Thank you
