Its kind of length to be embeded inside some support like column or something.its calculated using IS 456 :2000
Page 42. 26.2.1

Now description of the equation is probably as follows..
let dia of a bar is = d; tensile strength = s;and shear strength is =t;and length embeded in a wall is Ld;;;;
So to keep the bar to resist from sleeping from support
upto it's tensile strength the condion would be
(Ld*(pai*d))*t=s*((pai*d^2)/4) => Ld=(d*s)/(4*t)...

Answer / vishal

It's 50 times dia of reinforced bar.

Answer / arvind rai

the best is 50D

Answer / syed abdul rawoof

Answer / keshav kumar

Basically the column is a compressive member and use the
high grade conrete, so lap lenth is less than Beam.
