ABOUT THIS VIDEO :-
In this video Er. Akash Bohare & Corporate Trainer of Civil Guruji (Civil Engineers Training Institute) is Explaining About Basic Rules for Lapping length in Beam - Lap length in RCC Beam
The perfect zone for lapping is where the moments remain zero for continuous beams or in the bending moment diagram, where the values surpass the x-axis or remain at L/4 for simply supported beams. The lapping should be provided on tension zone as moments will be created with greater tension.
Lap Length | Lap length of Beams | Lap Length of Slabs | Lap Length of Columns | Lapping Zone of Beams and Columns. Lap length can be defined as the length that is provided so as to allow the overlapping of two reinforcement bars thereby ensuring safe and efficient transfer of load from one bar to another.
When we provide lapping in a column, all the rebars should be lapped in zone-B as shown in the drawing. The top and bottom portion of the column, i.e. zone-A ( L/4 length ) should be avoided as there will be a maximum moment in this zone due to lateral forces acting on the column.
This amount of overlap between two bars is called “lap length”. Lapping is usually done where minimum bending stress is encountered. In general, lap length is 50d which means 50 times the bar diameter, if both bars are of same diameter.
By far the best video on Beam lapping that too with practical demonstration.
Hats off to you sirji
Thank you

Hame bohat khusi hai ki aapko hamari mehnat pasand aai , Civilguruji isi tarah civil engineers ko aage badane ke liye mehnat karte rahega aur aap bhi knowledge dusro ko share karte rahe.
KEEP LEARING, KEEP SHARING.
Thank you sir I love civil guruji
Thank you so much for your good wishes. I greatly appreciate your love and support.
Keep Learning, Keep Sharing.
Thank s for good suggestion
Sir could you make one video for continuous slab reinforcement detail, how to place and tie the age of reinforcement where there is no beam provide at any side exemption of column. Means wall beneath of the slab
What detail. Pls .must one video for full detail.
Very good evening and thank u so much .
Sir when ever you will make these types of video upon my request pls dedicate my name we will be very happy . I will wait for your video .
Manoj surely I will make this video very very soon... Keep learning keep sharing
Deep information provided by you..Good job👍

Glad you think so! @ksshitiz22
Clear Span or Effective span divided by 4.what is correct
Clear span friend
sir Lucknow me training centre aapka kaha hai

Pl. Make a video on size of column and beam regarding span lengths
Thank you so much sir

sir IS codes kon kon se read karna cahiye for building construction batayega 🙏🏻
bahut informative video tha ye 👌🏻
Maruti bilkul iske upar bhi mai video bana dunga aap follow karte rahiye channel... Aur share bhi kariye apne friends se
Sir kon sa aggregates accha hota hai river sone Or lime stone
Thank you sir for giving such a good information
Good explanation
Thank you, Purander! I'm glad you found the explanation helpful. 😊 If you have any more questions or need further clarification, feel free to ask!
Yes jankari my friend 😮
Thank you for your comment!
We appreciate your support. We strive to provide the best Knowledge for civil engineers,
Very important video for all civil engineers
Thank you

Sir for bottom main reinforcement Lapp:-
from center of the beam we will avoid 50% length of the L/4 then after we will provide Lapp.
Suppose clear span 6mtr, L/4 =1.5mtr and beam depth 300mm,bottom cover 30mm, bottom main bar 16mm,
so effective depth will be 262mm.
2d= 524(2*262mm)
So, we will avoid from the inner face of the column 524mm and also avoid from the center of the beam 50%of the L/4.
So lapping area will be in beam.
We are taking length From inner face to center of beam=3meter.
I)Avoid 524mm from inner face of the column,
2)Avoid 50% length of the Second
L/4 =750mm
So= lapping zone area = 1.726meter(3Meter half span-524mm-750mm)
I think you will all understand 🙏
Thank you ao much.. I had some doubts even after watching this video. But your wonderful example made my all questions clear..
L/3 of total span 6mtr of beam

excellant sir
Sir, is one side of beam is inside the column and other side of the beam is outside the column. Is this an issue in column-beam joints?
Yes ❤
Very useful video .

What is the use of dividing them in 4 parts since u calculated the lapping distance from beam depth??

Thank you sir..or dusre beam ke videos for continuing beam is code ka bhi video banana
Yes sir
MashAllah Sir g
Suppose beam depth 300mm
Lap zone in bottom is - 200 -25-16 =159 multiply 2 yes or no pls help me sir
