(12+12+60) 12 dia of footing bar and 60 is the dia of clear cover till that i know after that there is another 12 also there na from where it is coming (ei 12 ) plz tell me someone
Length of longitudinal bar will be equal to {height of column from footing bed upto bottom of slab i.e 4m - (bottom cover + dia of transverse footing bars i.e 2x12) + Total development length (top + bottom)}
Sir u r doing good work for all civil engineers 👍
Sir You're so great Civil engineering student from Philippines, you save me
Your my real teacher and mentor thank you sir I'm from Pakistan
Thanks for the good lecture
It's very useful 🙏👍
Very Good, Thanks
Very good information
Really thank you sir you are the best .. and also pronunciation understood very easily sir
This was magical
Thanks sir
Thanks
your tutor is nice!. we can add different size of bar weight together?
their costs and purpose are different. Revise it again
For 135° neglect 2x3d in lateral ties cutting length
Kiya hai hhai
S,,for 135 degrees taking 3d,, you are correct,,
I think there will be deduction of 2*d bend at 40 d near the bent up bar of Column Continuing into the slab and same at the footing
muze 1 doubt hai sir 135 degree per 3d lete hai to 10d kyu liya
Y se @ se T etc. What means sir
D.L at the bottom end =16d=d is the dia of longitudinal bars
16×25mm=400mm
300mm I am confused
Please. teacher clearify that
Me to
❤❤❤
Sir, Why didn't you subtract 2 bends in the cutting length longitudinal bar ? Can anyone explain it to me
This is a mistake bro
(12+12+60)
12 dia of footing bar and 60 is the dia of clear cover till that i know after that there is another 12 also there na from where it is coming (ei 12 ) plz tell me someone
It is because we have 12 mm bars in both L and B direction. There for deduct both, I.e (12+12+60)
Please give the Longitudinal bar formula please
Can you please tell what is 25 (in 40 *d)
It's diameter of bar
Same question me
95kg steel use for one column
why i can use dia of footing bars twice ( 12+12+60)
May be it is for 2 sides so it will be 2x12
Because footing is 2 crossing layers of bars which forms a mesh.
Sir why you added 12 two times in first step of finding length of longitudinal bars, isn't it be -(12+60) ?
Same doubt sir
Weight of longitudinal bar ... diameter 12 square why not ?
40d = (40*25) where does 25 comes from??
25 is the dia of longitudinal bar
Its 12 how come 25
The footing bar are 12mm
The (4) longitudinal are 25mm (he stated verbally)
And the lateral ties are 8mm
40d =40X25 ? .. WHAT IS THE 25 ?
I made 800 likes 😛
Longitudinal bar size is 25mm or 12mm
I enjoyed your lesson but you are being too fast and not being an Indian speaker the ascent is difficult for me to understand. Thank you 🤝

Why 12 is added 2Nd time again
12mm bars provided both ways in footing
We don't need to add the top cover because that's included in development length (40d) from top side
Length of longitudinal bar will be equal to {height of column from footing bed upto bottom of slab i.e 4m - (bottom cover + dia of transverse footing bars i.e 2x12) + Total development length (top + bottom)}
Reply me sir
Steel wastage calculation add for 3% ur using 5% it's wrong
