LNG column is l/b greater than 12 or l/r greater than 40.

If slenderness ratio is lies between 12 - 60 then its short column. For greater than 60 it long or slender column.

l/r = 50.

Long column (l/b) > 12.

or (l/r) > 40.

l = Effective length.
r = Radius of gyration.
b = Least dimension.

l/r is slenderness ration and it should be > 40. So 50 is the answer.

It is not mentioned 50 anywhere but only greater than 12 is for long column, so 50 is not the exact option.

Please anyone explain clearly how come slenderness ratio of long column is 50?

Vishwanath Charantimath said:   10 years ago
Answer for the question is, long columns slenderness ratio is greater than 60 as per is 456 2000 page 42 clause 25.3.1.

Your is wrong. Long column can be said when slenderness ratio is > 12.

Guys if Left/R min>40 then column is long. R min = Radius of gyration.

So option C is correct.

If Leff/LLD >12 then it is a long column.
