Basic Rules for Lapping length in Column - Lap length in RCC Column

Excellent explanation

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

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

Best Engineer yes sir sir❤

Great sirrrrrr

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

It's 50 x 25 = 1250 not 1270

Excellent video. Keep it up.

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

50x25=1250

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

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

ততহ

A

Thanks For Teaching Sir (50 x 25) = 1250

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

Multiply krne ata hi nhi bhai

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

location not mention betweem beam/slab

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
