The basics of post tensioned concrete design | how to design post-tensioning

It is critical that all structural engineers understand post tensioned concrete design. within this video I will be covering the basics on post-tensioning design:
- How much post-tensioning should you have
- general design considerations
- minimum and maximum requirements for post-tensioning
- how to design an efficient post tensioned slab
- Sizing of post-tensioned slabs
Prestressed concrete and Post-tensioned concrete share the same benefits, by overcoming concrete greatest weakness.
This will hopefully help you to start to unlock the power of post-tensioning.

Awesome video Brendan! There was a lot of new information there I had never come across previously or thought of. Cheers!
-
Great video about PT, plus bonus content of the pour joints!
-
Good work Brendan. "Basics" but thorough and not off point. So good seeing structural engineers giving back. From a PT designer in Melbs.
-
Thank you Braden! We are learning from you.Glad to know you are from Austrelia.Waiting for more video.Regards.
-
The PT master strikes again :) Bravo Brendan
-
Thank you Brendan. I just realised I have missed this video last week. Can you please make a video on different types of structural joints ? How do we decide when to use temporary/permanent joints ? Really appreciate your effort and time.
-
As a PE in the states, it’s hard not to notice that 70 year old Seelye on your shelf. Keep it up!
-
Great video Brendan, the way you present it makes it easy to understand. More power to you. Also, if I can request you to make a video on how to read structural drawings from scratch that can also include the P/T as well. At last, thank you so much for making this video and spreading the knowledge. Cheers
-
Awesome video, very knowledgable. Is there any chance you could make a video regarding slab joints preferably for suspended slabs? I.e., TMJ's, PMJ's, construction joints, etc. It would be good to also explore why TMJ's are located between in-situ walls and slabs. Thank you.
-
Thank you, very helpful points. I would recommend for any one that least experience with PT to watch this video.
-
Super helpful thank you
-
Awesome video Brendan Are you able to cover permanent/temporary movement joints in future? I guess slab shrinkage in general and the absolute limit. Some engineers believe if you have a high degree of crack control (loads of reo) you can get away with no pour joints/movement joints..? Especially where there's two stiff elements such as cores apart in a slab, I've seen no joint introduced in between. Hopefully you have time to cover this in future. Keep up the great videos
-
@brendan thank you for the very informative video. Could you please explain a bit more of the drape in cantilever? It's still unclear for me of how secondary effects work
-
Great vedio...keep up With the good contents....newly subscribed your channel and really admire your work. 👍
-
Great video, but it'd be even better if you talked abit slower and extended your pauses slightly.
-
Hi, Mr Brendan. Will it work if i use 25T car hydraulic jack for T beam pretension that uses 5mm wires. Thank you.
-
thank you really useful
-
Very informative video, thanks B.H...Just wondering if you could help with info on approaching design strips for flat plates in RAM concept. Thank you.
-
Thank you
-
Is it still efficient to use load balancing method?
