Having used the same system almost 40 years ago except it was a single 19 strand stress at a time and only from one end , the only time we double end stressed the cables was if we did not get the required extension on the cables and then we stressed the other end and went to 10% then straight to either 70% 0r 90% cant quite remember which it was , i find it strange at 4-31 that the video seems to imply that a second "cheese" was applied to the back of the stressing jack , and a second series of collets / wedges , when i seem to remember everything was built into the jack
good video it helped me alot. but i have one doubt sir..there is no contact between the structure and the strads or tendons. then, how it works? sir.plz reply..
If you noticed, the profile of the strands / post-tension cables which is similar to a simply supported bending moment diagram. Once jacked and released, the tensioning effect of the cables compresses the set of concrete girders. The middle portion would experience uplifting. So, to answer your question, it is the contact between the strands with the openings that forms the whole mechanism to keep the individual girders in place. Not to forget the shear keys between the girders as well.
greatest mystery solved.. I can sleep peacefully tonight.. thanks for such a great explaination.
same
Always read the instructions, you may wish to turn the music off if this is your first attempt at post-tensioning.
Watch video solutions of engineering questions to expertise your knowledge of engineering!
Thanks for specialist explaining their specialty for generalist.
Watch here dear
Without "musik" it would be (much) better ! ! !
They just have an audio imbalance, and I think the music is poor. It's too loud, and bad lol
Thank you and Hats off for sharing the practical knowledge....
Why did you spoil such an informative video with BGM. Not able to listen due to disturbing background music.
Bütün teknolojik gelişmelerin bu korkak İngiliz eliyle dünyaya yayılması zoruma gidiyor
It look like that this method is complicated and not as strong and durable as other methods.
True
good job.
fucking job
Music is very annoying. Comes in the way of listening to and understanding the audio speech

What kind of adhesive is used between segments?
The title should be pre-tensioning...

Right dear
Engineering presentation and they use a 10^5?... 195 GPa is easier to relate to.
Watch here bro
