Bridge Works
Under what situation shall engineers use jacking at one end only and from both ends in prestressing work? - During prestressing operation at one end, frictional losses will occur and the prestressing force decreases along the length of tendon until reaching the other end. These frictional losses include the friction induced due to a change of curvature of tendon duct and also the wobble effect due to deviation of duct alignment from the centerline.
