Question

The diameter of the lateral ties in a column shall in no case be less than

• A. \(12\,\mathrm{mm}\)
• B. \(16\,\mathrm{mm}\)
• C. \(6\,\mathrm{mm}\)
• D. \(20\,\mathrm{mm}\)

Hint:

IS 456:2000 specifies \[ \boxed{ \phi_{\text{tie}} \ge 6\,\mathrm{mm} } \] and in some cases not less than one-fourth of the largest longitudinal bar diameter.

Answer 1

The Correct Option is C

Step 1: Recall the code requirement. According to IS 456:2000, the diameter of lateral ties in a reinforced concrete column shall not be less than \[ 6\,\mathrm{mm}. \]

Step 2: State the correct answer. Therefore, \[ \boxed{6\,\mathrm{mm}} \] is the minimum permitted diameter. Hence, \[ \boxed{(C)} \] is the correct answer.
