Calculation of Prestress Force

Hi Team,

I am trying to find a reference where I could see the process a prestress force is applied on a beam. I am investigating a post tensioned cantilever bent/pier design.

I have seen Midas Civil documentation where they are dividing each beam into smaller elements and applies an UDL due to prestressing. It is closely related to load balancing method to analyze prestress beams.

See below for reference.

Hello

Have you seen our online bridge design training? There you will find detailed information on the prestressing process.

I saw the video but it does not explain how the prestressing force acts on each of the element. The methodology followed by the program remains unknown to me.
