I am using Beam elements for the tendon due to its geometry.
as shown in the pic attached.
Since I cant use the embedded option as this would be fully constrain and wont be apple to do a cohesive element because the tendon is inclined.
any other suggestions ?
when concreting is done using ducts for the tendons, then tendons doesn't comes in contact with concrete, and hence no bonds formed. All the forces transferred to the concrete by end blocks.
The solution equation of the problem i.e. pre-stressed with unbonded tendons needs to be done through an iterative procedure because of material and geometric non linearities and cracking.
follow this literature

Thanks,
Well the tendon in the experment was covered with a plastice tube to make sure it is not bonded
