Question

According to $\text{IS 456 : 2000,}$ maximum slenderness ratio for a short concrete column is

• A. Less than 12
• B. Between 12 and 18
• C. Between 18 and 24
• D. More than 24

Answer 1

The correct option is A Less than 12

Short columns are those which fail primarily due to material failure. Short columns do have buckling effect, but of a limited value. Long (slender) columns are those which fail due to the material failure and also due to buckling.
According to IS : 456, a column may be considered as short when both slenderness ratios $\frac{l_{ex}}{d}$ and $\frac{l_{ey}}{b}$ are less than 12.
