The Column sizes doesn't change much using post tensioning. why have you shown such major changes in column sizes at the end of video it is after all a small change in dead load of building.
I am a CA working with a Construction Company and this video is presented so wonderfully that a laymen like me can also understand the procedure very easily.

a big hug whoever you are.....1000 clap for this video....education system & govt should see this & learn from this & realise that...... ......"Engineering to mujh se behtar aap jante ho,Main toh aapko yeh padha raha tha ki, padhate kaise hai"
AN INNOVATIVE TECHNOLOGY OF POST TENSIONING HAS BEEN EXPLAINED IN VERY SIMPLE AND SYSTEMATIC WAY THROUGH THIS VIDEO.

Manoj Issar 👍👍👍
the best video ever, thanks a lot !
don't we usually leave an opening for the stairs before pouring concrete in the slab? wouldn't breaking the concrete to build the stairs, expose the slab to danger of damaging it?
Studying for my GC exams, and this video totally helped in grasping PT basics! Thank you!
Great animation. Nice
I have already subscribed for practical.
By far, It's the best video ever seen. Detailed and very easy to understand! Thank you for posting!
Hi
@@gautamsiri1593 Do you play fortnite
I do
My mom took my laptop so I cant play roblox anymore sorry
U are very talented , sorry I have no post for a toy-player in my institute otherwise I would keep u there to teach graphics to youngsters ..
Great job, very good video presentation, very good knowledge
Glad you liked it!
An opening in a slab would not be poured and then removed. It would be blocked out and tendons either stress in the opening or stop at the opening (or going around).
That’s true engineering !!! One of the best videos I have ever seen in civil engineering , in Greece we usually use pt on bridges
If you want, we can use pt in buildings in Greece as well.
One thing is unclear to me. When you apply tensile force to the strands, strands are extending with what is obviously elastic deformation. How do you keep the strands for not coming back to the previous state, and therefore apply the pressure force to the concrete? How do you lock the strands after post-tensioning, with wedges?
Nice work
It's enough to understand what we read in books after watching this video.
Thanks for awesome video👏
Super video and technology!!
You can learn PT Processes in just 7 min, its awesome.
Beauty of building technology
Excellent video! I watched a few PT videos and I can say that this one is the best!
Very informative and a good presentation...... Educational institutes should adopt such techniques.
Prestress Concrete so nice friend
Prestress concrete
awesome video on post tension slab
Glad you liked it!
Excellant. This solves all the hassles of using muldtiple strands in a conduit/sleeve. Thanks for the post.
good
True.. Nice catch.
May i ask what software did you use for the animation?
When I saw this 1st time,at that time i was in 12th (7 years ago) i didn't understand this technique, now I'm in M. E final year now I get to it is Prestressing of slabs
Excellent video! Very informative and helpful! Just one question, how to cut out holes on a concrete slab without touching all the steels? Aren't they already bedded inside?
Good observation. Actually it is just a conceptualised way of the activity. One has to protect the cables from damage while removing concrete. Thanks for sharing your views.
whenever cutting through a PT slab, you should have the slab section scanned first to identify where the PT strands are to avoid cutting them
So, doing this allows one to make thinner floor/ceiling sections, allowing for more room in between the floor and ceiling, which can also mean short distance between the floor and ceiling, since you dont have to accommodate for ceiling structural supports.
Huh. Is of no real use to me, but still interesting...
Why can't we leave space for staircase... Before PT
you can and you should.
Thanks for this great video, very well explained.
post tensioning system explained in a very simple video so that a layman can also understand it.
فديو ممتع للغاية... ولكن اسأل كيف نسحب طرف وعندما نكمل السحب ونملأ الفراغ بالأسمنت گراوت كيف نقوم بفتح فتحة في السقف ولم تتاثر الأسلاك عند القطع علماً بانها سائبة في بايب داخل الخرسانة
i have learn a lot from this movie
Thank you
this is precast concrete column: ua-cam.com/video/avCQ0P435ks/v-deo.html
Thanks
With which program did you make the animation?
Sir , why don't leave a space 4:45 instead of removing of concrete again ? It gets waste of concrete.
If you have noticed, that portion of video is for having cutout in a slab which is already been constructed. It shows how make a cutout in a PT Slab. If such sections are designed before construction then that is considered earlier itself.
Thanks For Teaching Sir
Wowww....amazing.... It is like bridge construction technology....Thanx for video 👍👍❤
When stretching the cables, are they pulled sequentially for convenience, or randomly for tension distribution?
sequentially
Rahul incorrect. They are stressed in a sequence to distribute the forces for the shoring to handle the loads. Refer to the engineer of record and PT designer/supplier

Ravi Pandey what?
Ooo that' a mistake created in my child
which software or app or application did you used to make this building
Where is anti bursting rienforcement..???
Very good video presentation and post tensioning System is definitely going to revolutionize the construction industry in India.
How u make these animation.please say how.Using which software. All ur videos are so good.
The video is fantastic in explaining prestressed concrete but the music is loud and very distracting. Also, the video is very fast .
nice video
Scary while flat slab reinforcment failed
Excellent Sir.. Keep making👍
There is no beam in this construction..???
sir you have to use unbounded material what is brand and cost of material
Which software you using sir to make this vedeo pls tell me
I'm curious for such an amazing informative session which software was used?
I dont think its navisworks
It is Adobe Aftereffects.
what program was used to make this presentation
Angle grinders or cut off saws are not approved methods of cutting tendon tails on elevated slabs, only slab on grade.
very well done
Thanks to you and all.
Wonderful job sir.

I am little confused.Is there any one to help me.
Excellent animation video. ..good for civil engineers.
In case of earthquake all those will break 100%... and then what you will do? every building needs a good consolidation and in the same time flexibility.
The Getae Dacian can i ask if you have any evidence of post tension slabs being more likey to collapse than a coventional slab? interested in learning more
@@breakingrefractory5967 the same said some engineers in 1977. en.m.wikipedia.org/wiki/1977_Vrancea_earthquake
@@Ngmone i went through the link shared. No where it is mentioned about prestressed or post tensioned building failure in it. Secondly, the system has improved a lot in comparison with 1977. Please do not spread such misconceptions.
@@ptsindia that how it looks in the video, is the same system like the suspended bridge is made, the only think it looks is not exactly for an earth quake, don't take it like an offence but we wish to see more videos how it proceed in case of an earth quake in real life. Thank you
Excellent video work I really appreciate it
So creative idea. I would prefer it.👍
Can i please know which software
Very useful video for learning students
Glad to hear that
Is it possible to build a 10-12 ft high rubble wall by covering with this wire net in a hill area of 60 degree angle? Will you please tell how much will be the approximate coast coast for wire net of 12 ft ht 50 ft long?

Please tell me what program did you use to make this
Qual o programa foi usado para fazer esta animação?
wow..masha Allah.....its best video in the seen
XD bây giờ ko khác gì Empire State với tòa nhà Chrysler ngày xưa. Bây giờ thì mua nhà trên Amazon, thích nhà nào thì mua rồi họ sẽ ship đến tận nơi tất nhiên là phù hợp quy hoạch. Kiểu người máy biến hình lego, nhà cao tầng thì khung nhà từng tầng đc cẩu lên lắp ghép. Hoặc thuê thiết kế xong thì chuyển qua bóc tách thành modul và mua sẵn thuê dịch vụ lắp ghép kểu lắp điều hòa 2 cục . Chưa kể bây giờ còn có máy in 3D in vách, kiểu gì cũng ok kiểu đặt bánh sinh nhật hay lắp cửa nhôm kính, đại khái có máy cắt + khuôn sẵn. Cái khó nằm ở vật liệu thay thế xi măng cốt thép, nó phải rẻ như xi măng + thép nhưng mang tính chất của nhựa vì dễ định hình + nhẹ. Đại khái cát phải bung lên như bỏng ngô còn thép bung như đế giầy adidas ultraboost-tổ ong, hay nike air. à nhớ ra kiểu nhà tiền chế ở KCN. M cũng ko có thời gian đi sâu nghiên cứu nhưng mà cứ nhìn mấy cần cẩu xây nhà cao tầng, nó chính là 1 dạng gần giống cấu trúc tổ ong để chịu uốn + chịu nén và còn 1 phần ngắn phía sau gắn vài tấm bê tông để đối trọng --> suy ra cấu trúc khung nhà như video ở trên cũng vậy, sao để đối trọng đc hoặc khung nhà ở trên dùng cách làm cầu dây văng để tăng khoảng cách giữa các dầm cầu mà vẫn an toàn về cơ học. Như vậy chỉ cần đổ trụ nhà rồi dây văng giằng với nhau còn vách thì bằng gì thì tùy, sàn thì làm cong cong bằng thép đỡ ở dưới như mấy cái cầu ấy.... tóm lại là phải bung đc cát + sỏi để tăng thể tích gấp chục lần trong khi vẫn đảm bảo cơ học như vậy giá thành sẽ rẻ hơn chục lần , bung luôn xi măng .....
Best video👌
Thanking you all. Wish you all liked it. Please share it with your friends who are in civil engineering and structural engineering.

It is Adobe Aftereffects
I'm interested in Exterior and Interior Design, I was in confusion that Which software is too learn & Which software was in Demand n future.
firest look for Revit or Archicad for building design, and secondly use 3dsmax for furniture and accessories to be found online and added for the interior space, and third is the easiest 3d render software is lumion 10 ,, and at last, i hope this info will help you
Can you please Tell me name of this software
Excellent demo. Can u tell me which software make this demo? Thx!

Nice one mate
Everything's great...Please jst remove the big watermark in the centre of the screen... it's annoying
This is awesome
Tensioning the steel at time both side or only single side?
It depends on the design (based on the losses) as well as practical considerations such as an access of stressing etc..
Awesome video for getting understood 👌👌
Please make a video like this"how a building constructed" from foundation to terrace ✌️..... Also for multi story building 🙏
Ну да
thank you!
it is wonderful presentation of post tensioning system for building.
6:37 is that how much it differs or is it just for comparison effect?
ឭ
lmao
what softwware did you use
Muito interessante, parabéns aos idealizadores dessa demonstração
Sir If you wanted to go on in construction field of multi low cost housings as multiplex then make use of high grade products and low grade products in ratio of 35 : 65 but the low cost material should be heated by mixing it with carbon and Sulphur to its melting temperature. T this will provide strength to the structure and building will not get rusted or collapsed. Then apply red oxide and fire resistant glossy agent mixed over the walls in 2-5 or 3-6 coating. This will prevent the building wall from being contaminated and collapsing. Yeah Tera ghar ye mera ghar kisi ko dekhna Ho to fit manga le Teri Nazar meridian nazar
Super i understood very well sir good video
Really informative, thanq
What is the name of the program? Do you have free version.?
This presentation is good but not all process is right
ya..that presentation dont show when install that conduit we must put bar chair to get that profile before install pc starnd and after stressing we must do the grouting work
