Question

A concrete member under control compressive load is called pedestal when the ratio of effective length and least lateral dimension does not exceeds.
1. 3
2. 6
3. 12
4. 60
5.

Answer 1

Correct Answer - Option 1 : 3

Explanation:

• As per CI.26.5.3.1(h) of IS 456:2000 defines pedestal as a compression member when effective length of the compression member is less than 3 times of The least lateral dimension.
• As per Cl.25.1.1 of IS 456: 2000 defines a column as a compression member when the effective length of the compression member exceeds three the least lateral dimensions.
• For pedestals (l_e/D < 3), a minimum reinforcement of 0.15% of the gross pedestal area is provided.
