What is the minimum slenderness ratio of short column (according to IS:456-1978)?


a) Less than 12

b) Between 12 to 18

c) Between 18 to 25

d) Greater than 24

Correct Answer – a) Less than 12.


When the ratio of the effective length of a column to its least lateral dimension does not exceed 12, it is called short column. Slenderness ratio is the ratio of the length of a column and the least radius of gyration of its cross section.
