Answer to Question #236148 in Mechanical Engineering for Muhammad

Question

1. Under what situation shall engineers use jacking at one end only and from both
ends in prestressing work?

Answer 1

In the following scenarios, jacking at one end is used: When the expense of prestressing is more essential than the amount of prestress lost, a bigger loss in prestress is acceptable. When the exact profile and stress distribution of a parabolic cable can be compromised, or an asymmetric stress distribution is desired.
