Prestressing tendons

[sfr]

Same problem/solution as in this thread:

Warning about tendons

Like Tomaz said, there is no point stressing from both sides. The friction losses due slip (when wedging) carry past half the tendon. So stressing from the other side just mirrors the cable force. E.g. After first stressing from right red and after second stressing from left blue: [bild] You probably have relatively short tendons.
