# If the diameter of longitudinal bars of a square column is 16 mm, the diameter of lateral ties should not be less than

A. 4 mm

B. 5 mm

C. 6 mm

D. 8 mm

This Question Belongs to Civil Engineering >> RCC Structures Design

1. option C IS THE CORRECT ANSWER. The diameter of transverse reinforcement of columns should be equal to one-fourth of the diameter of the main steel rods but not less than 6mm.IS 456 cl 26.5.3.2 part C.2

2. Diameter of the lateral ties should be maximum of;

1) 1/4th of the main bar and
2) 6mm
So the answer here should be 6mm.

3. Lateral tie=1/4*longitudinal dia..
Or
=6mm... Which evere is max
So 1/4*16=4mm , so 6mm is max...

4. Correct answer is 6 mm
