Check for tendon elongation

Question:

Dear Sir,
For both end prestressing,the elongations on each end are not equal.


Answer:
When the tendon profile is unsymmetrical along the length of girder, tendon force after immediate losses (friction) will not be same at both ends, thus tendon elongation are not same.
So, when tendon profile is kept symmetrical, tendon elongation are same at both ends.

As the tendon profiles in the model are unsymmetrical, different tendon elongation are obtained at both ends.
When G1-T 01 is made symmetrical, same tendon elongation are obtained as shown below.
