@Adarsh.

How this comes? Is it in code?

AdaRsh said:   9 years ago
For
M15 58d
M20 47d
M25 40d
M30 38d In tension.

How to calculate 58d?

Please give the correct explanation.

Formula is the 0.87fyxd/4tvtbd so tv & tbd value is 1.5 then answer is 58 d I think.

I think the grade of concrete should be M15 not M150.

But as per the formula mentioned in IS Cods it depends on the grade of steel and bond stress. How can one comment on this without know the grade of steel?

Abhishek said:   1 decade ago
In which clause of IS code 456:2000 is this given?

Bivash said:   1 decade ago
It's depend upon bond stress, grade of steel, dia of bars.
More than Ld.
