Tomorrow m having my xm ...tried to search videos & found urs ...& I think I didn't hv to study bout prestressed concrete at all..I understood very clearly & I can write it of my own...thnq so mch☺
All the best for your exams👍😊
@@Technicalcivil thank you...😊
Mera exam aaj h🤣
Today is my exam
Are ye to Mai likhne wala tha same 😂
Good class for pre-stressed concrete. Both type pre tensioning and post tensioning
Dhanyvaad bhai bhot acha samjaya aapne, exam mein kafi kaam aya, lga ki College me fees waste krne se acha apko usme se kuch pay krdete, wonderful job 👍🏼
This is one of the best channel for civilians.....thank you sir....🙏🙏
Tq so much sir.. Aapki vedio dekneki baadh total doubts clear.. Ho gaya...
When initial stressing and final stressing to starrt , and how much strength concrete will achieve in both case.
What a nice explanation. You have cleared my all doubt in one video. Thank you so much Sir ❤.
post tentioning mey, grouting ke baad hi tendons ko cut kiyajayega na? kyo ki cut karneke baad phir tendons ka tention jo hai o khatam hojayega baad mey grouting karke kya phaaida hai? please tell me the procedure
Pre tensioning generally large no. Of repetitive members k liye krte h but aapne idr bataya ki large span k liye krte h jbki post-tensioning large span griders like bridges m krte h
Thank you so much bayya... Your way of explaining is marvelous.
Which one is best how many days required for pre tension to remover
Sir, what is the procedure for selection of pre-stressing and post-stressing? Which one to select when? Does it depends on any other conditions?
Sir
Kya pre-stressing ka limit hota hai
Ydi hum jayda pre-stress krte hai to kya disadvantages ho skte hai.
Pole me kaun sa method use karte h
Pre tensioning or post tensioning
Sir, which one is better pre tensioning and post tensioning ,and why ?????
Sir fir v agar deflection hoga thora sa v toh bhi to crack aa hi jayega....crack toh aayega hi kisi bhi kimat pe kyunki thora sa deflection fine cracks toh aayega hi..kya ye bs koi accident ya failure ko rokne k liye hota h..
Mind-blowing Bhai today you cleared my confusion completely
Sirf pc strad use karega ? Ya normal steel steel bi rehega ? Pls reply
I was confused about why beam gets deflected upward even though we apply the uniaxial tension.. now its clear. Thanks alot
Love and respect from Pakistan 💚
P.S: Is there any analysis problems videos of prestressing?
Hlo bhai ab kya kar rahao ho aap
Sir great ...simply define tipical chapter
There is any affect on concrete after cut of tendon wire like cracks, decreased in concrete strength, etc...?
Hi sir
Strength kisme zyada ayega?
I have one question on post tension. What is the compound the duct is filled with. Because if the duct is trough and trough from one end to other then only random wires can be put and if they don't stress the beam then it is no use. So the holes must be so tight that with post transitioning it must pull the main beam structure otherwise no use. Pls explain and which is better for casting pre or post. Pls compare.
Sir, agar hum Fancing ke liye pole n penal banana chahte hai to usme pre stresses system se banaya hua hi chaiye ? Prestressed system se banaya hua pole n penal me upar niche wire cut karte hai vahase jung lagke pole ko vo creck nahi karega ? uska koi solution hai ?
concept clear ❤❤❤ video Nice.....
Sir i was very impressed with your video regarding prestressed concrete its very informative and simple salute u sir
Bruh... In post tensioning... The ducts which are provided doesn't damage the beam after releasing or cutting the tendons..?? Like cracking n all.?
Sir , we manufacturer rcc pole for fencing pole , and other cement products ,now I am starting a new unit so I want to make prestressed pole . How much strength it increases than rcc
Sir when prestress is done beam deflects upwards.. but why cracks are not developed in top surface
...actually it should develop cracks na?
Sir tension release krne se beam niche v deflect kr skta h n ?
Upar hi q krega deflect?
Thanks for defransiatae pl tell us method of stressing and it calculation also thanks
Which one is best pretension or post tension, reply sir
Very nice explained sir
Sir bohat badiya smjhaya 🙂👍🏻
Bhai I am Software eng .. though i was wandering why Beam will only bend in one direction?? it can bend downards also ?
Sir deflection to niche bhi ho sakta hai, aisa kon si arrangement set up karen ki deflection uper ho
Please make a separate video about the difference between pre tensioning method and post tensioning method. And which method is more suitable for structure.😊
Pre-tensioning and Post tensioning both are effective under their own circumstances. Post-Tensioning is generally preferred for slabs especially in commercial buildings like malls, IT Parks, etc, whereas, pretenioning is used basically for the infrastructural works like in bridges the girders are pre-tensioned at the casting yard.
Nice teaching sir 👌👌
Nice teaching...nice concept clear
Vry nice teaching sir
Hello , we learned about modular ratio and all that is based on the contact between concrete and reinforcement..I would like to know how this entire modular ratio and other design factors get effected (or remains same ) in post tensioned concrete since there is no significant contact in post tensioning .
Good teaching
Sir why post and pre tensioning...are these both have same strength?
Lightweight lightweight walls ke liye kaun se chemical Milaya jata hai foamconcreet kya hota hai
Good teaching skills sir
👍👍best teacher
Bht badhiya hai bhai.... Maza aa gya. Aese hi video dalte rahein...
Sir bean upper ki taraf hi kyo deflecte hoga?
Superb explanation 👍👍
Explanation is very good ...Sir numerical ki video bhi upload kr dijiye...
Nice ..easy to understand 👍
Why Or where Or time when we can use pre stressed concrete??
Hi. Post ten maximum how much can be settle down?
Super bhaiya , and your way of explanation is super , ❤️ from AP
When we cut the bar then how to say is go to only upward direction
While it may also go in downward direction
Sir post tension ki process me kitna pesa lgta hai up to 5000 sqft tak
Sir such member can we use in slab beam
Thanks sir for your nice information
Beam niche ke taraf deflect nahi ho sakta hai kya
Excellent explanation. 👍
Sir i had a question that if tendence is used in the beams then there is no need of providing reinforcement bars to the beams ??
Covering material hota kyaa hai
Nice way to explain
Pre stress concrete ka final strength ka kitna percentage one day strength hota hai.
Tq so much sirr...superr explanation..
super explanation 👍👍👍
If this cable strand mistakenly cutted
Then what thigs we can do?
reply fast
Nice explanation
Very good bro.
super effort.
Excellent sir
Can we use fe-415 in prestress concrete. Explain
Sir you are great
So nice discussion
I want to known calibration of hot mix of plant (not batch mix plant) drum mix plant & calibration & deference of by weight calibration & material flow calibration which which plant to apply...
Sir, supper explainetion
Metro u girder I girder me HT strands ka use krte h ..
Beam mai Kisko khicha jata hai reinforced ko ya phir kisko
Thank you ji achha samanjh aaya sir
Sir after cut the tendons why the span not deflected to downwords
Plz add design of rainforcment soil......
How to know Desire strength are achieved??
Useful video, Thanks
thank u so much sir !!! excellent explaination !! its prestrees !! now clear my doubts!! 👌👌
Thank you sir this channel helped me a lot
Very very thank you sir 🙏
Sir plz make video about Deflection of prestressed concrete member..long-term and short term problem
Why the backforce does not break the concrete?
Please next part with mcq of Prestressd concrete
Well explained
Thanks sir , very useful video
thank you bro for the information
Sir, please make complete series on design of Prestress concrete
Uses & advantages,disadvantages
Thank you sir you have cleared my doubt in a minute 🤩
Struggling start of my sem now i have understood 😂
Sir m y soch rhi hu ki agr humna beam pr jyada tention da diya tb vo fail ho gya to 🤔🤔
Advantage and disadvantage of this process?
Pre tension me .. after removing the tension. ..agar beam niche deflect hua to
sir numerical bi krwaiye please jisme sare concept include ho
When tendons pull in tension from both side then that time beam in compression?
