The situation of maintaining lapping zones asper the codal provisions will be difficult under situation of providing dowel bar for longer span beams,where we need to cast the beams later stage of project.The couplers are very useful under these situations. Also wastage of reinforcement bars will be higher for maintaining lapping zones asper IS codes.I prefer to cut the reinforcement bars of the following lengths 3m,4m,6m,8m
Don’t use 6m for your ease. Try using beam length 3.2m beam depth 450mm with 20mm rebars used as main rebars and 8mm as stirrups. Then you will realize the cons and its difficulty. Although whatever you said is true but sometimes in certain cases it is not feasible as the lapping zones seems to coincide almost within the same zones
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?
But in our site the lift lobby area has a beam of 200×1240, which witdth to depth ratio is 0.161, is this a design mistake? or this rule can be break in some special cases, please give answer sir.
Sir for 20 feet span 6 no's 16 mm rod is used in beam for g+2 house .In between 20 feet distance pillar one small pillar of 4 no's 12 mm resting on underground beam also provided just 6 feet away from centre pillar ..it is ok or need to add more steel.?beam depth 14inch +6 inch slab thickness.column is 4 no's 16 mm &4 no's 12 mm

सर यदि बीम का क्लियर स्पान 5 मीटर हो और बीम 700mm डेपथ हो और उसमें 20 एमएम का सरिया लग रहा है तो फिर उसमें किसी प्रकार की कोई जगह ही नहीं बचेगी। उस कंडीशन में क्या करेंगे
Sir beam top main lap center main aur beam bottom m side lap kyo dete hai aur yah bhi bataye ki Beam m top main s.f. aur b.m.kha aata hai aur bottom m kha aata hai aur as per is code. Aur 13920 ka 2016 revision hai aur aap 2003 ke according bta rhe h
If the 2d length fall beyond L/4 then what to do sir? I mean if 2 times of our beam depth is 40 inch and L/4 distance is less than 40 inch which one should we follow?
Sir aap jo Is code use kiya hai wo 2003 ka hai aur iska latest revision 2016 ks hai aapne is video m clearly nhi btaya hai ki beam bottom m kha pr aur top m kha pr lal dena chaiye so plz sir mera req hai ki aap video dobara banaye jisse muje bhot help miligi. Aur sir reply jarur dijiyega.
Some missing points.IS 13920 FOR BEAM CASE. 1.The Factored axial stress on the member under earthquake shall not exceed 0.1fck 2. The width of the member shall not be less then 200mm.
Please make a video for Overlap length kya lo gai for billing k liye. (One floor pr) 1)Over lap 32 Dia se reduce ho kr 25 mm ho gya . 2) over lap 25 Dia se increase ho kr 32 Dia ho gya .
Aise cases may always take d as your smaller Dia of bar and rest things are same .koi special Ld nahi Hoti hai bar ki dia. Change ho to refer IS 456 2000 U WILL HAVE BETTER KNOWLEDGE
Column में Bottom area में L की length कितनी होती है और क्यों???? Example Bottom mash dai 12mm both side Clear cover 50mm Footing depth 600mm Column bar 16mm Ld = 50d = 800mm So L = 800-(600-50)-24=226mm पर ये तो कम है।।।। और अगर आप 300mm कहना चाहते है तो क्यों??? हर जगह जवाब ढूंढा, नहीं मिला, पर आपसे उमीद है।।।
From bottom of beam to centre of main bar, If Cover 25mm & Main bar 20mm than 25mm + 10mm = 35mm effective cover, also if beam depth 600mm than effective depth of beam = 600mm - 35mm = 565mm, Clear

Good morning Sir, Is improper position of bottom bar lapping in beam can crack the underneath brick wall in future?
Great information sir thanks for sharing,what if one beam crossing perpendicular to each other but no column below junction
Dear Sir the Clause No. 4.4.1 you referred in the video is from which code ?
Plz tell
Sir ham 2d bina chode nhi kar sakty hai lapping.
Near by column m?
Kar sakte h, lekin stirupps / ring ka spacing 75mm c/c rakhna over all lap length par
@@FactualCivilEngineering thank for your reply sir.
Sir lapping zone of slab p v video banao plzz

Ye 1.3time kya hai sir
Sir if lap length fully cover inside column lapzone, it is safe
Yea it is safe we can say, but shouldn't be at joint face in any case as per is code

check it
Sir tell us about lap length for welding a steel bar.
If the 2d length fall beyond L/4 then what to do sir? I mean if 2 times of our beam depth is 40 inch and L/4 distance is less than 40 inch which one should we follow?
Did you get your answer bro
❤❤
U r taking 50% of moment at half of 2nd L/4 .how that？does -ve BM starts at exactly L/4 from the column face？
exactly
Sir aap jo Is code use kiya hai wo 2003 ka hai aur iska latest revision 2016 ks hai aapne is video m clearly nhi btaya hai ki beam bottom m kha pr aur top m kha pr lal dena chaiye so plz sir mera req hai ki aap video dobara banaye jisse muje bhot help miligi. Aur sir reply jarur dijiyega.
Some missing points.IS 13920 FOR BEAM CASE.

2. The width of the member shall not be less then 200mm.
Please make a video for Overlap length kya lo gai for billing k liye. (One floor pr)
1)Over lap 32 Dia se reduce ho kr 25 mm ho gya .
2) over lap 25 Dia se increase ho kr 32 Dia ho gya .
Aise cases may always take d as your smaller Dia of bar and rest things are same .koi special Ld nahi Hoti hai bar ki dia. Change ho to refer IS 456 2000 U WILL HAVE BETTER KNOWLEDGE
sir,please upload about the Right Method for Placing of Lapzone in Column Reinforcement.regards
Sir top m jo lap dena hai uske bare m aapane details m nhi bataya h
At the end you said the spacing should be min 150 mm however acc to IS code it should be max 150mm
It's not exceeding 150mm. He said minimum 150mm by mistake.
less than 1.3Times below. What is this plzz explain
Sir 300mm ho tho
Drawing ke bare janna hai ditel se mughe nhiata hai
Amit ur friend
Column में Bottom area में L की length कितनी होती है और क्यों????
Example
Bottom mash dai 12mm both side
Clear cover 50mm
Footing depth 600mm
Column bar 16mm
Ld = 50d = 800mm
So
L = 800-(600-50)-24=226mm
पर ये तो कम है।।।।
और अगर आप 300mm कहना चाहते है तो क्यों???
हर जगह जवाब ढूंढा, नहीं मिला, पर आपसे उमीद है।।।

Sir clause 4.4.1 jo l/4 ka explanation diya he vo samaj me nhi aaya thik se
Effective depth clear nhi samjaya bro
From bottom of beam to centre of main bar, If Cover 25mm & Main bar 20mm than 25mm + 10mm = 35mm effective cover, also if beam depth 600mm than effective depth of beam = 600mm - 35mm = 565mm, Clear
From bottom ki from top sir
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?
