thank you for sharing my question is how do you relate the footing design to the earth pressure
Thank you very much Sir. i like the way you are teaching.
Welcome bro
hello sami, you have not subtracted the hook lengths of 2D in the first steel calculation. aren't we supposed to subtract the lengths caused by extensions and bending?
when you calculated 12mm xx & yy axix lenght may be it will ,L=3000-2*side covers+2*300-(2side*2*top &bottom*)
so,L=3000-2*100+600-4*50
L=3000-200+400
L=3200
L=3.2m
tnx
L:3.3m
10 min wrong calculations i. e. (3000-2*50)/200 +1 =15.5 ==16 nos of bar
Thanks alot v.helpfull video
Bend bar cover should be times to 4 because of top and bottom and two sides, also minimum concrete cover for footing on ground should be 75mm.
Hi sir, thanks for the videos. i want to ask that how can i find out the volume of bar. Thanks
thanks for the video sir but if 50mm is concrete cover and multiply by 2 for top or bottom so is the one side i think it should be multiply by 4 to minus the both side top and bottom concrete cover
thank u for your lesson. can u please explain at the time of 6.26 why did u only multiply 50 by 2 instead of 4. thank u
thanks for the beast teaching
Sir ,length of vertical bar
Why you subtract cover at top 2 times. I don't understand what is the need of subtract side cover to get vertical length...
Please answer
please estimate a residential building (framed building)
I usually follow your videos it is useful, but try to provide one video regarding design a project 3 or 4 storey house structure design Manually it very important point I need also .
Sir I have doubt about slope in road construction if the height of road is 6m then what should be horizontal distance of ramp slope
Sir I have used 12mm rods in columns in ground floor only but now I want to build 4 floors on ground floor , can I use some reinforcement in columns so that I can construct 4 floors on ground floor
hlw Sir here I just want to know how to find out "Developement length of bar of a column into the footing"...??? plz reply must
Thanks sir..
I,m Emmanuel I,m civil engineering student ,If possible for next sessions you can teach us about indeterminate , determinate structure analysis and reading well building plans
Great dear very good Estimation

Gud mrng sir,To know me how to calculate steel in Apartments with exactly,Mats and columns ,please tell me sir.
thank you
Is that vertical length calculation 5.0 m is right
Please make a full video of estimation and costing of a building.
Thank you sir g
Sir pls ..sho how to calculate quantity of steel for 2 steeped footing.
Explain the steel , cement and sand needed for the residential bukiding
length of main bar would be 3000-cover+9d ???
Very nice sir
3. Even you didn't deduct 2 side bend angle. It should be deduct as follows if 90° angle we have to follow Biritish standard formula .It means 2d "d" mean dia. 2*12=24mm for one side, so two sides to be deduct 24×2=48mm
Brother pls Upload Design of Steel
A. O. A
Brother frustam pera mid column ka steel estimate lagany ka tareeqe upload kary
Thank you sir
plzz do fast , now m waiting 4 yr second vdo
make a more vedio and more detail about civil engineering
bhai bbs aap ne footing ka jo kiya h , usme top or bottom kaise nikalenge wo btao na aap plzz
Engineer if u have any raft foundation drawing detail plz upload
Really awesomeeeeeeeeeeeeeeeeeeeeeeeeeerreeee
Pls upload a video on BBS of two way slab.
osm sir
How can I know how much of the diameter and how many times it takes to load so much
hello sir how we calculate no of bricks in well
Duration 2nd step means vertical length of steel calculation have doubt
why are provideing bend rod or L rod in footing and column
Thanx alot
Good teaching
6. Cutting bar length is 2900+400-48mm =3252mm (each bar cutting length is 3.25m)
Thank you
5. Cutting Bar Length= (effective length + Both side Bends) - Bend angle Deduction
Think you sir
Nice one
Sir please how to read constructn drawing ki video bnaye layout ,column coordinates beam column sbki plz
sir building construction ka brick and ston masanory and timber ka lecture upload Kare plz sir
Dear 7500 psi pr kitny manzil building bana skty hn or grade 53 kitny psi ky barabar hota hy.
actually bbs m top or bottom bhi calculate krte h na to aap ne kha kiya h , sir
sir mujhe estimating bridges and culverts ke numerical problem me chaiye
Please make distinctly vision for viewer
4.Effective length = 3000-(2*50)=2900mm
can you please post a video of doing this estimation in excel.i mean complete estimation of a building using excel with the structtural drawing
Can you help me
That is a very big footing!
Sir how to calculate bbs of trepezoidal slope footing
Sir Where does 12 dia bars used in footing
Plz sir explane thumb rule
and sir Civil drwing
the general i cannot see the board
What about stirup weight
Am not sure to my understanding, L=3000-2covers + 2*(300-2covers)
L = 3000-2*50 +2*(300-(2*50))
= 3000-100 +2*(200)
= 2900+400
= 3300
=3.3 M
No of bars =( 3300/200)+1 =(16.5)+1
=16 +1
= 17#12-200c/c
correct
श्रीमान मुझे bbs पर डिटेल्ड वीडियो चाहिए,एकदम डिटेल,जिसमे सारी जानकारी हो।एक फ्रेशेर से लेकर एक एक्सपर्ट तक का नॉलेज हो plz
8. Finally you have to add some % of wastage. 3% wastage is recommended for steel other common materials 5%.
I was asking also taking off a building with footing
Sir can u explain as per diploma C20 sybullas quantity surveying 2 good explanation
Nice
there is something wrong with that lecture on stirrups. it does not show any video. plz check it.
estimate for culvert please
Massonary footing ke video banalo Vai wo bhi aaj
2. So both side bend length to be 600-200=400mm
If any distance of column is not givrn
I think No. of bars is Incorrect..
Please Re-check 16mm bar length calculation
Aur bhi estimate ki bare main bataye sir..
Ok bro
Thanks sir. The process is cool but the answers are wrong. Please check well your operation
dear sir
length of column
L=3000+700+300-50+300+300-100=4450
say 4.45M
plz reply sir
I also noted this big silly mistake by sir.
same anwser 4.45
Can anyone tell me about why sir subtract 2* side cover at top
According to my opinion top cover of column is subtract not side cover... & it will 3000+700+300-50+300+300-50=4500
I think plz check footing length (300*2=600-(2*50 top and 2*50 bottom 200)=400+2900=3.3m length
nice ex
where is the bending factor?
Here's the simpliest way Lt= L+4(sidecover) = 3000+ 4(50) = 3200mm/3.2m
7. And you tall total 15 bars on x direction but it should be 16 bars. As follows (3000-(2*50))÷200= 14.5 ,so 15 bars + 1 bar = 16 bars.
Why u add +1 for which reason
How the length of the reinforcement of the vertical section is 5 meters?
and, the number of bars in the footing is 16, not 15.
I think these are some mistakes in the tutorial video. Thank you.
Yes 16 bars not 15
deer sir the number of bar is 16
You asume the length of hooks iqual to h-2sides cover, this principle is not always fulfilled.The rest is ok congratulations.
+1 kaisai koi btayaiga plzzz...?
First over all length 3.4 is wrong
Bend deduct nahi kiya
3.3m
Inka clarity ga chepuu bro
Column top cover minus NH kiya..and column cover 50 pakda hai..it will be 40....
Dear Sir may i know your mail because i would like to keep touch via email
First?
Thanks
Kindily explain the basic concept underlying in selecting different diameter for vertical bars here discussed as 16mm and base as 12mm .similarly as other experts in the example selected 12 mm verticae & !ask 8 mm. Kindily explain I have not been able to under stand.

WWRegards
+1 is for what?
column spacing is missing
Pls mke in excel sir
