During prestressing operation at one end, frictional losses will occur and the prestressingforce decreases along the length of tendon until reaching the other end.
These frictionallosses include the friction induced due to a change of curvature of tendon duct and also thewobble effect due to deviation of duct alignment from the centerline.
Therefore, theprestress force in the mid-span or at the other end will be greatly reduced in case thefrictional l
