Questions and Answers

What is the condition for providing minimum shear reinforcement in the form of stirrups?

  • $\frac{A_s v b}{S_v} \leq 0.87 f_y$
  • $\frac{A_s v b}{S_v} \geq 0.4 \times 0.87 f_y$ (correct)
  • $\frac{A_s v b}{S_v} \geq 0.4 \times f_y$
  • $\frac{A_s v b}{S_v} \leq 0.4 \times 0.87 f_y$

In which scenario is shear reinforcement provided in the form of vertical stirrups or bent up bars with stirrups or inclined stirrups?

  • $\tau_v < 0.5 \times \tau_c$
  • $\tau_v > 1.2 \times \tau_c$
  • $\tau_v < \tau_{c,max}$
  • $\tau_v > \tau_c$ (correct)

When will the section need to be redesigned according to the given information?

  • $\tau_v = \tau_c$
  • $\tau_v > 0.5 \times \tau_c$
  • $\tau_v < \tau_c$
  • $\tau_v > \tau_{c,max}$ (correct)
