Q: Diagonal tension reinforcement is provided in a beam as:
  • A. Longitudinal bars
  • B. Bent up bars
  • C. Helical reinforcement
  • D. 90⁰ bend at the bends of main bars
Correct Answer: Option B - This tension which is caused in the tensile zone of the beam due to shear, at or near the supports is called as diagonal tension which is caused by shear, cannot be resisted by concrete alone. So shear reinforcement is provided in the R.C.C. beams to take up diagonal tension and prevent cracking of beam. • Diagonal tension reinforcement is provided as Bent up bars.
