IS 456 2000 clause 25.3.1 explained about unsupported length, not for short/long column.

I think 40 is the correct answer.

As per IS 456 and SP16 (clause 3.4 of compression members) if Slenderness ratio leff/LLD is more than 12 it is a long column. For steel structures, the Slenderness ratio is Leff/r min and its limiting value is 180.

S. N ratio for short column <41 or =41.
And for long column >41.
And for long column >41.

Yes, that means Slenderness limit should not exceed 60. Beyond that limited, a column can't be considered.

According to IS 456:2000 (Clause no.25.3.1).
The unsupported length between end restraints shall not exceed 60 times the least lateral dimension of a column.
The unsupported length between end restraints shall not exceed 60 times the least lateral dimension of a column.

According to is 456 2000, for long column λ should be less than 60.

This is based on l (effective) /radius of gyration.
