D. 50 is correct.

L to lateral dimension > 12.
Or.
Slenderness ratio greater than 120 is a long column.

For steel, long column it is Greater than >50.

According to IS: Code 456-1978.

S.R .is less than 12 that's called a short column.
And S. R. is equal to up in 12 that's called long column.

Use IS:456-2000.

@All.

"The unsupported length between end restraints.

Shall not exceed 60 times the least lateral dimension of a column.

IN THE ABOVE LINE ITS NOT WRITTEN THAT IF IT EXCEEDS 60 THAN IT WILL BE A LONG COLUMN.

ACCORDING TO IS CODE 456, PAGE NUMBER 41 CLAUSE 25.1.2 STATED THAT;

"A compression member may be considered as short.

When both the slenderness ratios Lex/D and Ley/b are less.

Than 12".

SO, SLENDERNESS RATIO IS;

(EFFECTIVE LENGTH/LEAST LATERAL DIMENSION).

Pedestal =less than or equal to 3,
Short column= between 3 to 12,
Long column = 12 to 60.

Please explain how it can be possible? I can't agree with this answer.

Please explain why answer 50?
