The horizontal distance between parallel main reinforcement bars shall not be more than three
times the effective depth of solid slab or 300 mm whichever is smaller IS-456.

Determine thickness of the slab from the consideration of limiting stiffness. The pitch of such reinforcement shall not exceed 5 limes depth of slab or 60 cm.

Yes, right @Baloch.
3Depth in Main steel And 300 mm whichever is less.
Distribution steel 5Depth And 450 mm whichever is less.
As Per IS 456.

Ii question, it's said should not exceed.
Means it's maximum limit. 3d is minimum. It should not be less than 3d and more than 6d. Right.

3 times the efficient depth but not more than 600 mm in case of main bars. But in case of distribution bars 6 times the efficient depth.

The same qn was asked in a recent Kerala psc exam. The key showed 6 times as an answer. Is there any explanation for it to be 6 times?

3 times in main bars or 600mm - whichever is smaller.
5 times in transverse or distribution or 600mm whichever is smaller.
5 times in transverse or distribution or 600mm whichever is smaller.

Pitch S.S slab.
Main bar - 6d.
Distribution bar - 4d.
Pitch continues slab.
Main bar - 3d .
Distribution bar - 5d.
Main bar - 6d.
Distribution bar - 4d.
Pitch continues slab.
Main bar - 3d .
Distribution bar - 5d.

3d or 300mm for main steel.
5d or 300mm for distribution steel.
As per the latest Amendment of IS456.
5d or 300mm for distribution steel.
As per the latest Amendment of IS456.

No, the correct answer is 5times. Wdistributeduted bar is 5times more than and 300mm spacing.
