- Short RCC column, =< 10.
- Long RCC column, > 10.
- Short Steel column, =<50.
- Intermediate Steel column >50 & <200.

Lef/b >12 called long column and Lef/b <12 short column.
But I don't know which economical column please tell me 1 circular 2 square 3 rectangular 4 octagonal.

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.

The ratio of effective length over least lateral dimension is greater than 12 then its called a long column your ratio is for steel structure.

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.
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.

I also agree with all above answers, because IS said that if slenderness ratio is more than 12 then the column is considered as long column.

As per IS-456 is slenderness ratio is less then 12 then only column is called short column. This ratio is basically for Steel columns.

FOR LONG COLUMN - Ratio of unsupported length between end restraints shall not exceed 60 times the least lateral dimension of column.

If it is l/r less than equal to 40 short column.
Then according to question answer should greater than 40.
So, answer will be 40.
Then according to question answer should greater than 40.
So, answer will be 40.
