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?
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?
Its very good and useful for site supervisor and Forman
Glad to hear that
Sir thanks aap ne bahut Engg ko savara he

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
Thanks sir for your explanation with all those neat diagrams, I'm very thankfull to your as i have applied your explanations in the field....As a fresher it really helps me a lot...... Thanks again....
You have gread conversation style sir
mukesh bhai great explanation
we are proud of you explanation
Thanks sir
great job.....keep it up
sir please check the top bar(extra bar) calculation in both section A & B...
overlapping length minus hogi ya add hogi..
Watch here more
very nice
BBS as per execution and structure design.
Good job man .. you Delights of all senior civil engineer. You makes easer process of BBS.
I'm addicted this all videos
Carry-on .. God bless you.
Thanks
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?
Thanks For Teaching Sir
Sir o video my ny Kal dekhe hy....samj geya hon
Thanks.
The best explanation of rebar calculation on RUclips.
Please upload an advanced vedio using a portion from real drawings on raft foundation, colmun, beam, retaining, core and shear walls.

Thank you sir... good work.. keep it up 👍
Thanks sir I am waiting for next videos
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
Ok Thanku Sir
But.
what about #BBS if the reinforcement is #Doubly (DOUBLY REINFORCEMENT SLAB)
nic video. Give some idea about cutting length of bar
A great lecture for me...
Thank u sir Ji...
Excellent teacher. Keep up the good work.
Sir apki videos bht helpful h..Ek request h ki trapezoidal footing ka detail BBS bna k video upload kre plz
thanks once again. very very helpful video

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.
A great Lecture for me thanks u Soo much Sir
Sir plz one way slab ka video banaiye
sir , very good explanation .
thank you sir its very important lesson for us
Thanks a lots guru......carry on
Thank u brother
G one doubt in calculation of straight bar. Why your not subtract 90degree bend at development length?
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
Excellent sir...
top extra bar slab mein end par provide karte hai na?
all videos are so helpful bt sir upload one video on tender also difficult to learn by book so plz upload it if possible
thanks for your teaching..
Sir Plz tell me what is the spacing and Dia of Bar using in slab generally
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
Dear Sir, very much useful information. great job. please explain me where to give lap in slab with lap length. Thanks.
At l/3 or l/5 distance form end
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.....
And one thing more sir plzzzzz upload a video on continuous slab.....
Pier cap ke bbs pr koi video bnao sir
Its is soo helpful to me so happy and intrested to learn from you sir....!! Keep sharing more knowledge for us sir.... Love your class. ❤️❤️❤️
Learn more here
good slab shorter span & longer span alternate bars structure & cutting length # but still i couldn't understand does slab also has top & bottom bars like beam top & bottom bars ?????
sir upload one vedio about estimation. it will very helpful for fresher.
yes sir I really want to know that too
Have patience sir... i will upload everything with time
Ok. Thank you sir.
L & T - Learning Technology
Sir plz bathaavo
How can we design steel bars based on column & beam size for duplex home
Note : i don't have SBC of soil & load
Am asking like
In village side how do they decides bars to column & beams (without architect, load calculations, Soil bearing capacity
owsm video sir thnq u so much...
but sir we want a video on estimation
Sir but i find double layers of bars without crank in slab. Is there any advantages of providing double layer?
Thanks , we are waiting next video.
Thank u..so much...nice explanation....
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
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
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
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
i hope next video will be the BBS of dog leg staircase as well as circular stair case.....
Nice video thanks brother
Sir what about tortional reinforcement....it is not mentioned in drawning but i think it should be provided....
very useful sir
thanks a lot
Sir please upload the videos of Rate analysis of various items and labour productivity.
Hello Sir
All your videos are really helping out me in field. Thank you so much.
Requesting you to plz plz plz upload video for Detailed Estimation of Stone Masonry Compound Wall...
Plz plz
See here more dear
sir in straight bar you have add 50d which is more than bearing is that ok
thank you very much, very educational indeed. i have subscribed right away and hoping for more educational topics you will share in the future.
Thanks for videos
very useful video
Sir drawing se all site ki steel kese calculate krte h plz help me
Great job.
Best method
Very good lecture sir plz prepare a bbs of one way slab ?
Sir site pe Sariya kaise dalwayege ge men bar and dishtubution bar ..
Nice teaching
sir your video is very best .I appreciate you .but I want to know .
when you deduct bend in crank bar .so why don't deduct in straight bar ??
Are the straight bar are straight no have bent I mean development length . because the different of straight and crank bar only 2 cm thanks
