I am an electro-mechanical engineer having some experience in civil engg also. But reinforcement is a tough subject for me. I am now constructing my own house. Though I tried to get BBS or estimate for rebars, my supervisors, civil engineers or structural engineers are unable to give me a satisfactory result - they either do not know much or are not willing to work in this manner. In this situation, I am learning the subject through your videos and I hope I will be able to do the BBS and estimate myself, without depending on others. Thank you Mukesh for your sincere work for the sake of technology.
professional in field specially for individual houses just want to cokie cutting. They will try to silent you with exorbitant stories and then want a free hand. most of the architect or structural or labour contractor are same. The moment you cross check their work they get headache. you got to be lucky to get good one.
hows your house now?
Sir acha nhi laga balki bht bht acha laga,aisa lag raha hai tution padh rahe hai.. Thanku sir

I'm addicted this all videos
Carry-on .. God bless you.
Thanks
thank you very much sir aap humlogo ki itni help kr raha hai , god bless you. sir ji
Thanks apki duao ke lie
Thank you for these type videos. On this video I can't understand that why bends are not deducted from cutting length of straight bar?
top extra bar slab mein end par provide karte hai na?
hello i am riyazali shaikh from nasik maharashtra i am big fan of your page. every day i watch your episod. PLEAS UPLOAD VIDEO ON CENTER LINE PLAN
Good job L&K.. but please can you make this tutorials available in English. please. ASAP. thanks

F&U foru sir aap bhi to genius hai...
F&u same question is for u
Are vah aapke bhi ye sir he ? ❤️ I also ❤️ ur channel
Torsional steel pe video banaye sir
Very good sir jee..... thanks.....my name is Irfan from Pakistan.
best teacher ever :)
Thanks For Teaching Sir
It was amazing lecture 🥰loved it
sir one way slab me moment short span pr jyada rahata hai ya long span pr....plzzz answer me
Sir 26*20clear span slab me latak beam ya slab beam sahi rahega main and dist bar 10mm c/c 125mm 6inch thickness two way slab thik hai kya
Sir,
I see your both lecture i.e. cutting length and BBS. Very clearing lecture. I requesting to kindly upload Any Major Bridge BBS like ROB and cable stayed bridge.
Firstly, i would like to thank you for providing a great platform for all the Civil Engineer to study BBS through your videos.Secondly, sir you have been doing a great job(great effort and appreciation) hatsoff. Thirdly,with due respect,i want to request you to upload BBS of dam and retaining wall in your upcoming video.Thank you
jo 50d consider kiye hai...kitne gread ki concrete aur steel use kiye hain aap isme....
sir your all videos about bbs is very use full you explain very detail now I want to that you upload videos it have total slab of one drawing .s1 ,s2,s3....and b1,b2 like that
This video explained for thank you so much sir next like that come
Mukesh Bhai very very nice Video
Sir your videos very useful and helpful for beginners so plz upload more videos about Q.S
BBS of Slab(Two Way) is Bahuuuth Clear Explanation Hai, but what about the mesh at the four corners; please explain the mesh at the corners with a necessary diagram.
ramasamy jagannathan exactly sir even I am wondering with same
There is no speicific design for mesh...what he said is that top view looks like a mesh in corners due to the crank portion of bars in both directions meets and hence it appears as a mesh
sir i hope this same calculation is their for one side crank bar i mean method is same, just the bend subtraction is diff. right .? sir
G one doubt in calculation of straight bar. Why your not subtract 90degree bend at development length?
Excellent video. thnx a lot sir.
Ur teaching awesome sir...Staircase ka reinforcement .video banai a sir.
Sir please reply Sir apne bola h ki ek straight ayega ek bendup ayega but esa drawing me nahi diya isme sab bar bendup h but ulternate same direction me h i mean each bar bendup but in opposite direction
Sir apki videos bht helpful h..Ek request h ki trapezoidal footing ka detail BBS bna k video upload kre plz
Hi Sir! I like your way of explanation and it is very helpful for us to know BBS. There is a little calculation mistake in Top bar (extra) in L&T website but I'm convinced from your video.
Thank you very much for your video.
U welcome
Thanks sir I am waiting for next videos
Thank you sir, bohot acha laga, mera bohot help hua.
Sir upka section BB ka top bar ka ans i think galat hai, sir galat nahi to rply me samjha digie plz.
Sir but i find double layers of bars without crank in slab. Is there any advantages of providing double layer?
dear sir , Section AA Top Extra Bar is some miss understand. BCZ in video u said we should add 2x 100 for Lap. but in calculation u subtract the 200. its right or wrong. kindly clarify. plz
nic video. Give some idea about cutting length of bar
Thank you sir... good work.. keep it up 👍
Tq sir, but I have one question sir
In this Crank bar cutting length= use Ld ,But its not applicable for this single span slab sir? Ld length applicable in only continues slab with beam..
If we applied this Ld in single span it becames steel size longer than size of the slab
Excellent teacher. Keep up the good work.
Hi, Please let me know somethings.
If i consider the thickness of slab 130mm, Clear cover 25mm, then D=68mm
Then according to your law cranked bar length become smaller then straight bar.
Cranked Bar: 5000+(0.42*68*2)+(50*12*2)-(4*12)-(2*2*12) = 6161.12mm
Straight bar: 5000+(50*12*2)= 6200mm
if you change the Ld value it don't impact on the length to increase cranked bar length.
so i see straight bar is less then cracked bar. is that ok?
if i do anything wrong then please forgive me i am not from civil engineering .
Thank you
great job.....keep it up
very good sir, thank you but only thank you not enough for sir
sir , very good explanation .
A great Lecture for me thanks u Soo much Sir
sir please check the top bar(extra bar) calculation in both section A & B...
overlapping length minus hogi ya add hogi..
Watch here more
Thanks sir for sharing such knowledge... Sir I have one doubt please reply...
Sir is video me Apne section AA ke along (Main) steel find Kiya ...but Apne distribution steel section BB ke along find nhi Kiya h .sir ..
Please sir explain why.....
Hi Mukesh, I understood this slab BBS. It seems to be the slab for one room. But I have a doubt. Suppose I have a slab with 5 rooms. How the rebars are placed? Room-wise or as an entire floor? For example, if the room A is 5x6 and another room along it is 6x7, can we straight away place rebars of 12m (2x6) or do room-wise?
room wise sir... above beam we have to use crank bar
Thank you for this advice. Very interesting to learn reinforcement. I am now calculating floor beams and slabs....
sir will bottom main crank bar come in bottom at top , but you showed in bottom at top , i felt main bar always comes in tension zone surface and short span
Sir ek hi bar dono side se crank rahta hai , ya fir alternative bar me crank hota hai
Dono hi type ka ho sakta hain...
But generally one side kiya jata hain...
See more here bro
nice Explanation Sir...!!
thanks sir, yadi two span ka bbs nikalna Ho to cranck bar me lap karenge ya alag alag nikalenge please reply
lap kar sakte hai beam junction pe
Slab ki mesh ki sath aap agar beam & column ka jo joint or owhi chis keyse karna hota hay agar bata dete to mere liye accha hota. I'm waiting for this.
according to this video the development length becomes 0.6 m which is immpossible to execute pratically please give me the solid reason behind this i am waiting for your reply ....may be i am wrong please explain..
thanks once again. very very helpful video
Hello sir I have question that in IS 2502 code of bending and fixing the hook is taken as 12d +12d= 24d but in ur tutorial you use 10d
Excellent 👍
thank you sir its very important lesson for us
Dear Sir, what abuot the quantity of slab(conctrte), how much steel %age is used with respect to the volume of slab? And should we deduct it from concrete?
Dear sir,
in the example you are not extending rods in to other panel or bay of slab member but actually the rods to be extended to other panel and cut length varies depends p on continuous & discontinuous edge . will you post other video for that.Please clarify.
Kind Regards
Sainath
Thanks a lots guru......carry on
helloo sir.... sir aapke video bhut hi achche lge.. sir mujhe aapke ye notes ki xerox chahiye pdf me..please sir aap suggest kijiye ye kese milenge
And one thing more sir plzzzzz upload a video on continuous slab.....
sir ye straight bar distribution bar h kya
Thanks , we are waiting next video.
sir itna sufficient h na bbs aapne jo bataya h isse zada ki jarurat ni h i mean ye complete h na sabhi sites k liye ?
bbs drawing pe depend karta hain.
@@LearningCivilTechnology sir process n steps same hoga na jaisa aap batate h !
Dear sir,
I have small doubt not from this video general doubt which will be applicable to Slab bbs , suppose if span of slab is of 16 m say the rod length available in market is 12 m, then lapping to be provided for all bars, in this scenario what would be the maximum lapping percentage of bars at particular section & lap length as per IS code Please clarify. It would be great help for me.
Regards
Sainath
sir in straight bar you have add 50d which is more than bearing is that ok
all videos are so helpful bt sir upload one video on tender also difficult to learn by book so plz upload it if possible
Mukesh Ji, I have subscribed your channel last month and got fruitful information. I found no information on this - scenario based placement of Bars for better strength in slab(repeat formation after 4 or 5 side bars, not alternate)/beam/columns. Remaining Peaces should be placed at best possible places Bathroom/Kitchen/Rings/Chairs etc. It should be on Paper instead of site. I hope you will act on it. Regards
A great lecture for me...
Thank u sir Ji...
Excellent sir...
I have one doubts . If slab gose both ways through so what kind of extras bar.and how is bent up bar and destubition put sir
Thank you very much sir
your video and demonstration is nice please upload the videos of bbs bridge deck slab and dome slab details
thanks for your teaching..
dear sir very very thanks for your teaching . i request to you pls. slop slab reinforcement detail vedio in your web site
sir,same bar will be bent on the both sides？
Or it will be bent in only one side ？
Thats up to you. U can do alternate also.
Sir Plz tell me what is the spacing and Dia of Bar using in slab generally
Thank u sir..👍from kerala
Thank you. Your video collection how to all download
Development length of main baar ya crank baar column me lap hota hai binding k liye... Lekin column to sirf 4 hote hai corner par, jabki development length through out the slab hota hai..
Kya development length beam me binding Kiya jaata hai?
Lekin beam to slab k niche hota hai fir kaise beam se bind up kiy a jaata hai?
Please ise clear kare!
Great job.
Best method
Keep it up bro , you are going well don't leave this . God bless you 👌
Thanks sir. Bas apna asirwad banaye rakhe
Sir staircase Mai b main bar shoter span mai he aayega
