Question

As per IS 456:2000, the maximum spacing of vertical stirrups is to be limited to

• A. \(0.50d\) or \(150\,\mathrm{mm}\)
• B. \(0.30d\) or \(120\,\mathrm{mm}\)
• C. \(0.60d\) or \(160\,\mathrm{mm}\)
• D. \(0.75d\) or \(300\,\mathrm{mm}\)

Hint:

IS 456:2000 recommends \[ \boxed{ \text{Maximum stirrup spacing} = 0.75d \ \text{or}\ 300\,\mathrm{mm}, \ \text{whichever is less.} } \]

Answer 1

The Correct Option is D

Step 1: Recall the IS 456:2000 provision. According to IS 456:2000, the spacing of vertical stirrups in beams shall not exceed \[ 0.75d \] or \[ 300\,\mathrm{mm}, \] whichever is less.

Step 2: Identify the correct option. Hence, \[ \boxed{0.75d\ \text{or}\ 300\,\mathrm{mm}} \] is the correct answer. Therefore, \[ \boxed{(D)} \] is the correct answer.
