Prestressing coupler are commonly used in long span bridges with continuous spans. The couplers are provided at point of minimal forces (usually the point of contraflexure). 50% cables are coupled at one section and remaining are continued till next point of contraflexure.

After the first span is complete, cables are stressed and next span cables are threaded in couplers and we start pushing the segments of next span towards the coupled location - there is a large resistance faced in pushing because of the stiffness of the tendon (as the cables has to change shape during pushing). To overcome this difficulty often a slot is provided in the webs of segments adjucent to (next to) the coupler location.

If any one has faced similar phenomenon then request to kindly share here for benefit of all.
