Column c/c = 6000+6000 =12000 Column corner= 200+200 =400 so total length = 12400 lap length = 50d = 50*25 = 12400+1250 = 13650 - 50 (cover) = 13600 develop length (i mean L length ) = Ld ( 50*25) = 1250 = not consider the beam size bigger then L size so beam height 400 - (top & bottom cover + top steel dia) = 400 - (50+50+25) = 275 Total length = 13600+275 = 13875 This just for calculation steel full length 12.1M
Deduction of bar dia will come 1.90°bend = 3 nos ( 3×2d)=6 nos. 2.135° bend = 2 nos. ( 2×3d) = 6 nos Total 12 nos of dia bar need to be deducted.Otherwise your explanation was too good compare with other video.Keep going, it will useful of upcoming generation. Thanks and regards. G.Srinivasan
Brother he is Calculating upto end As our TMT Bar Steel length is limited upto 12m I mean after 3rd column there is Cantilever Projection So Total Length will be (developmentlength in first column+(6000+6000)+ eff.length of cantilever projection)= 17150 or not I too don't know what was the projection given so he summed up all these . & took this Overall length and deduct the remaining Part of Lap length... 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
Sir, 21:19 While subtracting the bend in the stirrup, you considered 5 x 90 degrees, but at the hook, the bend is 135 degrees right? So it should become (3 x 90 degrees + 2 x 135 degrees), which is (3 x 2d + 2 x 3d) = 12d, instead of (5 x 2d = 10d), right? Little clarification is required in this part, and yes, your work is helping me a lot. ❤❤
Sir ji, ap top aur botom bar ki length jab find kr rhe ho to (400-50) kyu kr rhe ho...apko (200-50) karna chahiye...kyunki clear span colomn ke centre se hai....please mujhe bataye...mai sahi hu ya galat.please
while calculating cutting length Already 200mm from column cross section is added with span of 6000mm So if we want to reduce cover in the sense we should do like 200-50 from remaining area of the span (200-50)+6000+1250 And it's not 16000 initially 200+6000+6000+200= 12400

Sir , I have been watching ur videos since 2018, took the online training u suggested n now I m an Govt Er. Can u please have a offline save option for your videos. It would help alot as i live in no netzone.
Sir बहुत-बहुत धन्यवाद । Top extra bar और Top main bar का L का length बराबर 850 नही रख सकते क्योंकि Top extra bar में spesher pin आने से ये बडा हो जायगा ।
Sir, I appreciate you that which you had uploaded video regarding BBS, at the same time in my opinion i want to let you know, if it possible can you provide us for the viewer through our link regarding BBS PDF file notes along with details drawing, if it possible the viewer concept will be clear definitely, if you could manage your time try to make another video BBS along with Pdf, i beg you earnestly.

Good civil site engineer keep it nice work by guys make one video for drainage cutting level as per DRG and mathology of work bathroom water proofing and drainage and plumbing pipes fittings in bathroom
Sir, footing column, beam slab wagera ki size or dimension kese find kare?? Agar hume koi new building banani ho?? Kya aap agla video iss topic par bana sakte ho ki kese size decide kare.
Sir super video no doubt... but sir practicaly samjhate to jyda better hota...Aur aapne kafi jaldi-2 chizon ko explain kra hai to thodi si problem aa rhi samjhne main!
Sir please make a video on how to design steel for slab according to load.... Ki load ke hisaab se hme kitna steel provide krna chahiye....kitna size rkhna chahiye slab ka
200+6000+6000+200 is 12400 mm. You have taken 16000 mm. Pl check column end to end is 12400 plus lap (1250-200) 1050 on each side. So total 12400 + 1050+1050 +lap is 15750 mm . You have taken 2000 mm instead of 200 mm .

Clear Height between plinth beam top and roof beam bottom-11 feets Zone-A-11/4=33 inches Zone-B-11*12-66=132 -66=66 inches There are 6 bars 16mm@4,12mm@2 At zone B top- 2 no of lappings At zone B middle(30 inch below top lapping points)-3 no of lapping At Zone B bottom (30 inch below middle lap point)-1 lapping Whether the above arrangement is allowble? Whether lintel tie beam can be provided any zone? What if lintel tie beam falls on zone-A top area?
(400-50)+6000+200?+3000+1000= ye jo 200mm hai column ka half hai lena jaruri hai jab adhi beam ki 3000 length le chuke hai to ??? Aur 16000+1000 =17000 kiye to use 16000 ki use kar rahe hai..
I love ur effort for making this type of videos sir ji👍but i hv one doubt sir in end extra bar y u add 1500+350 actually from the drawing 1500is enough but y 350also
Hello all this mathematics done by structural engineer right. I mean all details will be in structural plan. Or do you have to calculate on site per beam ?
Bhai bottom continuous bar ke drawing mei ek side 400-50 kiya hai usmei 200-50 hona chaiye mujhey lagraha hai nahi to lap lenth bhi double kiu nahi kiya
Sir ap ne jo ld bend kiya hai 400-50 Kyun Kiya hai.......400 ka to column hai to 350 minus hona chahiye....400-50(cover)=350. Please sir explain...... I am unable to understand.
10:12 minutes par jo calculation btao hai vo dubara check kre, 1500-400-50 = 1050,but aapne 1150 kese likha, jo calculation ki hai usme 1500-400-50= 1500-350= 1150 likh hai
![[Full] 4 ต่อ 4 Celebrity EP.920 | 3 พ.ย. 67 | one31](http://i.ytimg.com/vi/KwiW2M_kAg4/mqdefault.jpg)
Column c/c = 6000+6000
=12000
Column corner= 200+200
=400
so total length = 12400
lap length = 50d
= 50*25
= 12400+1250
= 13650 - 50 (cover)
= 13600
develop length (i mean L length )
= Ld ( 50*25)
= 1250
= not consider the beam size bigger then L size so beam height 400 - (top & bottom cover + top steel dia)
= 400 - (50+50+25)
= 275
Total length = 13600+275
= 13875
This just for calculation steel full length 12.1M
Good bro
11111l q
Ye video bnane wala abhi kacha badam h
Deduction of bar dia will come
1.90°bend = 3 nos ( 3×2d)=6 nos.
2.135° bend = 2 nos. ( 2×3d) = 6 nos
Total 12 nos of dia bar need to be deducted.Otherwise your explanation was too good compare with other video.Keep going, it will useful of upcoming generation.
Thanks and regards.

Sir ye aapne bottom bar ka vagre nikala hai vo cutting length nikali kya ?
Sir Mid extra bar me aapne continues column k both side aapne L1 distance s leke kyo calculate kiye hai.
Jabki L1 and L2 lena chahiye tha
9:07 1500-400-50
1500-450= 1050
And sir aapne
1500-350= 1150

Thanks For Teaching Sir

Thanks brother keep watching
@CivilSiteVisit sir aap ki koi app hai kya
Sir! Top ki sabhi bars ko ek hi jagah par lap kar skte he? Ya har bar ke liye alag alag karna hota he?
Cutting length of main bottom bar
Firsty calculate clear span length
= Effective length- 200- 200
= 6000-200-200
= 5600
Clear span length = 5600
When we calculate cutting length of main bottom bar( left side from lap)
= ( Ld+ 10db)+( clear span length)+(column length) +(lap length 50d)-(bend)
= 1500+5600+400+1250-50
= 10700
Right side from lab
( Clear span + Ld + 10db)
=5600+1500
= 7100
K
Are bhai...cover block se apko kya koi matlab ni hai😂
Excellent sir very helpful
Sir
Muze 1 confusion hey laping length 1250 liya hey lekin 1250x2 ayega kya? Kyu ki dono side se bar lap hoga

Sir please make a video on how to design steel for slab according to load....
Ki load ke hisaab se hme kitna steel provide krna chahiye....kitna size rkhna chahiye slab ka
Okay brother bnata hun don't worry
200+6000+6000+200 is 12400 mm. You have taken 16000 mm. Pl check column end to end is 12400 plus lap (1250-200) 1050 on each side. So total 12400 + 1050+1050 +lap is 15750 mm .
You have taken 2000 mm instead of 200 mm .
Total length of bar =12.4 m hai sir
Hmm yeh sahi hai
Brother he is Calculating upto end As our TMT Bar Steel length is limited upto 12m
I mean after 3rd column there is Cantilever Projection
So Total Length will be (developmentlength in first column+(6000+6000)+ eff.length of cantilever projection)= 17150 or not I too don't know what was the projection given so he summed up all these
.
& took this Overall length and deduct the remaining Part of Lap length... 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
G yehi sahi hai but wo by mistake hua hai ...

Development length is used to grip but lap is used to reduced tension. Is it right?

nice one sir
But sir ,200+ 400+ 200 kyo nhi centre bale column ki 200 ,200 deno sides nhi loge kya
Bhai development lenght m colum kaise ghtaynge wo to plus hoga na syd ek baar bhai clear kroge
5:55 pe sir 16 metre kaese possible h wahan 200 mm ko aap 2000 mm add kr diye hain kya ??
12400
200+6000+6000+200 = 12400 not 16000
12400....is correct
