GATE 2016 CE (CE2) – Question 17

Concrete Structures · Design and detailing of beams and slabs · 1 mark · Multiple choice

As per IS 456:2000, the maximum allowable shear stress $\tau_{c,max}$ in reinforced-concrete beam design depends on ______.

  1. grade of concrete and grade of steel
  2. grade of concrete only
  3. grade of steel only
  4. grade of concrete and percentage of reinforcement

Show answer and explanation

Correct answer: (B) grade of concrete only

Explanation

The maximum nominal concrete shear limit is tabulated by concrete grade, reflecting diagonal-compression capacity. It differs from the concrete shear strength τc used before shear-reinforcement design, which also depends on longitudinal reinforcement percentage. Therefore **grade of concrete only, B**.
