Q: The maximum distance between bars in tension in slab is
  • A. Three times the effective depth or 300 mm whichever is smaller
  • B. Three times the effective depth or 300 mm whichever is greater
  • C. Five times the effective depth or 450 mm whichever is smaller
  • D. Five times the effective depth or 450 mm whichever is greater
Correct Answer: Option A - The maximum spacing between two parallel main reinforcement bar is case of RCC slab shall be 3d or 300 mm or whichever is less. • Maximum spacing between two secondary parallel bar in case of RCC slab shall be 5 d or 450 mm or whichever is less.
A. The maximum spacing between two parallel main reinforcement bar is case of RCC slab shall be 3d or 300 mm or whichever is less. • Maximum spacing between two secondary parallel bar in case of RCC slab shall be 5 d or 450 mm or whichever is less.
