Q: Which of the following steel reinforcement does not act as a shear reinforcement in RCC beams?
  • A. Bent up portion of longitudinal steel
  • B. Stirrups inclined (at 45") to beam axis
  • C. Stirrups perpendicular to beam axis
  • D. Tension steel parallel to the beam axis
Correct Answer: Option D - Shear reinforcement will be necessary if the nominal shear stress exceeds the allowable shear stress. • The code recommendations are– 1. Shear reinforcement in the form of vertical bars, known as stirrups. 2. Shear reinforcement in the form of inclined bars (45º). 3. Shear reinforcement in the form of combination of stirrups and inclined bars and bent up portion of longitudinal steel.
