#CivilEngineers
Lapping length for column
what is lapping length in column
dia of lapping length
formula of lapping length

[@sanjeevapampana4535]

Correction please,50x25 is 1250 and not 1270 which you specified.

[@sulemansikander5161]

Yes

[@U.W265]

I really like your approach, best tutor ever, keep it up sir

[@pradeepbharti6643]

Your video is very important for all fresher civil engineers

[@mohantisso4234]

very very nice explaination

[@karanparihar8238]

Yr Mai new hu es field Mai..... Or Apki video bhout ache lgte h or Bhout Kuch Seekhne ko bhe milta h sir.. Thanku soo much sir

[@CivilEngineerss]

welcome bro

Sir khah sy ho

[@binodpoudyal983]

U have good knowledge to give lecture in civil subjects .l always with ur tution.

[@er_noyda9613]

@9:18 25×50= 1270 that is wrong 25×50=1250 OK

[@johnchiao4804]

hahahaha!! what is that?????

[@er_noyda9613]

@@johnchiao4804 .awwwww broooo I'm joking 😡😂😂😡

[@KGNBOYSCREATION]

Right bro mai bhi yhi bolne wala tha

[@MAnas-el6cd]

Excellent video. Keep it up.

[@AhmadAryan2013]

Question about rule 2: To find over lap length, Do we use lesser dia or the top rebar dia?

[@Kushkamili]

Engineer thanks for the lesson

[@moddycontris5672]

Thanks for the lesson, I have got a lot of idea brother, God bless u,

[@phyohtetkoko929]

Thanks For Teaching Sir (50 x 25) = 1250

[@itsahmad936]

Nice video very helpful But u have small mistake 50*25=1250 not 1270

[@khademulmursalin9898]

50*25=1250.check it again

[@tapasbhunia8895]

Bro focus the concept.

[@sanjeevayadav4146]

Keep rocking performance sir,it will be useful for each and every civil site engineer, please upload videos sir in structural and plumbing and electrical and waterproofing.

[@nuwagabacollins6837]

Best Engineer yes sir sir❤

[@tariqmir1401]

Very good knowledge thanks brother

[@Bhattnadim]

Awesome explanation bro !!

[@agiti]

i like your vedios but u can make good amount of views if u use some modeling vedio for this lapping case

[@dulhapur]

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?

[@agiti]

guys i gat some real question i need to get only clear 25cm over my ready made columen reinforcement wichnos 14mm diameter having 6 bars 20x30 mm dimesion . so should i use 1.3 factor when making the overlapment?

[@nivruthi]

Sir , if we hv to join the bars above 36 dia what we will do...,sir and also plz explain tilt bars on other video if possible ,based upon situation ,so im following ur videos,by this i can grab.tq so much sir.

[@harikahoney3816]

If dia is more than 36 then we go for couplings....

[@nivruthi]

@@harikahoney3816 tq. Harika !

[@Dannyndangili]

Please provide a video on how to know the number of bars needed in a slab

[@donaldcharles1535]

Great job . Very informative.

[@anandreddy953]

Well explain bro..thank u

[@henrygoltiano4716]

Very helpful

[@pradipadhikari3078]

If all diameter bar of column is not same than what lapping length should we kept??

[@manikantakarri3317]

Why we provide c/c distance is 1.3 times of lapping length

[@puiteakhenglot4537]

Sir i have one question,what is the. Formula for 10mm 12mm,16mm and 20 mm Like you said in this video 20 mm is 50d

[@nickma8049]

What if lapping length exceed lapping zone how would you deal with it ? Let say Hn is 3.3m and diamater of rebar 20mm then Lapping length is 1m and lapping zone is only 1.65m but rebars should be 0.3*lapping length apart with each other

[@aliqadri4672]

What you mean by hn..??

[@huzaifkhaliqhuzaifkhaliq4367]

Great sirrrrrr

[@Iitgstr1]

Thanks Bro 👌 for useful information,

[@neelakandapillai3072]

Excellent explanation

[@homendrapandey5708]

God bless you n yur job,sir

[@edwardarikpe9403]

Please is it proper for lapping in foundation before DPC level?

[@Axumman]

some times you said the formula is 24d and sometimes 50d which is the right one. the same thing to beam L by 8 and L by 4. very confusing

[@Muleaddis]

Tnx for ur video , but i have a question that on the previous video u said the lapping length is 40D but now u said 50D ....which one is right

[@bharatsinghrathod4968]

50 is right

[@altamashshaikh2703]

It is not fixed, it varies for different columns...It is given in structural drawing

[@islamicofficial1056]

40D is for slab only and 50D should be for tensile zone of beam or slab

[@girishhiremath4066]

Sir 50D for 25mm dia is 1250

[@vinilbrdbro5140]

Good video. Thanks

[@kevinombock9536]

Then also talk about the stirrups at the lapping zone of the column

[@jeyakumar9194]

Sir good and explain the labing Jone

[@muhamedsedik1629]

For diff. diameters. Do we take the lesser or the top?

[@afonrinwoolubunmipius6881]

Well done pls. Show some practical examples

[@mohammedafsal5876]

If column have 8 bars. And how many bars want 1.3 times of dia length.

[@ismailfaleye6060]

What is the purpose of the 6D little length and also what do u mean by plinth level

[@khalifaalnaamany9330]

Assalaam Alleikum brother, i need your help i have build a foundation of 3 store building, the problems are some of the steel bar exposed from the foundation beam are shorter than what is required are shorter than 50cm the steel sizes are 16mm, the formula of lapping 45d gives 72cm and some exposed bar are less than 50cm, how can i solve this problem.. Thank you

[@dulhapur]

For finding A zone and B zone in coloumn only two floor beams are considered,is not lintel tie beam required to considered?

[@abdurrahim3605]

it is very important

[@jasvirkumar5817]

In which situation or circumstances we can change dia of bar. Is it safer.

[@sheikhhafiz8325]

Why lapping is not provided for steel bar havind dia>36mm, what is the reason

[@islamicworld1477]

Very informative vidoe sir

[@mangmang1532]

Wa alaikum salam Broo..indonesia

[@vigneshpandiyan8231]

Bro you have given the lap bend up length as 6d, can you say at what angle it must bend or is there any formula ?

[@johnchiao4804]

i didnt see in the construction site doing like that why??

[@tofansahu4015]

Again thank Brother

[@aliqadri4672]

Sir is that 1.3 is for stagered bar in colums.??

[@rajeshsaha11r]

Nice explain but is code recommend after 32 mm dia of bar lapping not 36

[@aliqadri4672]

Sir 6D is for that any bar wich we gonna tilled ???

[@dailyhacks2244]

Bro isn't the lapping length more, means I haven't seen they provide 1.2m lapping length in any site and 6d (250)is bit more

[@invisiblehovercraft3218]

Yes

[@HabiburRahman-xt2gl]

Do not allow an advertisement in the technical educational teaching of your good video. It seemed to be very worst.

[@ijazmuhammad8399]

25×50=1250 mm and now we need in meters. 1250÷1000mm in a meter=1.25m overlap comes here.

[@panneerselvam4161]

Sir actually 4 coloumn rods 2 rod same height and another 2 rod c/c distance 1.3*50d height correct pls tell

[@muktaramhalder9882]

Correction plz,,,50*25,=1250mm,,,but you,,are, showing,,,1270mm,,,why,,,?

[@huggituppa2544]

If number of bars are more than 8 how can provide 1.3 times dist bitween 2 laping centers

[@paklahisap2646]

In the other Video you put 45D and in this 50D for lapping length

[@michaelmelocoton8197]

25x6= 150..sir is it in centimeters or millimeter? Hoping for your answer..

[@mohammedabdulwahab2922]

Millimetres

[@lokpalmore2296]

How to provide other bar

[@Anjo1515]

Thank you bro.

[@syedabdulaleem5299]

location not mention betweem beam/slab

[@rajashehzad8739]

If top steel is 24 mm dia and bottom steel dai 20 mm dia then which one we take for finding lapping length

[@mohammedabdulwahab2922]

Actually we take lesser dia of bar not top dia of bar👍

where is the proper lapping position of the column span? and why?

thanks

What could happen if we provide lapping length in the same point?

At the same point Buckling may occur

24mm will not available in market. After 20mm next available is 25 mm only.

[@binodkumarranjit219]

50 * 25 = 1250

[@rosanmaharjan6811]

Sir I think ur calculation is not practical because laping zone not to be a zone and 1.3m different means how possible in zone b

Nice

common how much lenght is the lepin lent!! i am waiting!!
