Q. The ratio of diameter of reinforcing bars and slab thickness is
Solution:
According to IS 456:2000:
- The diameter of the reinforcing bars shall not exceed one eighth of the total thickness of the slab.
- The mild steel reinforcement in either direction in slabs shall not be less than 0.15% of the total cross-sectional area.
- However this value can be reduced to 0.12% when high strength deformed bars are used.
- Thus option D is the correct answer.
