Question

Effective length of column fixed at both end as per IS 800 shall be​

Answer 1

Explanation:

Both end fixed: The effective length when both the ends are fixed is equal to . The effective length factor is equal to 0.5. When one end is fixed and another end is pinned for a column, the effective length is equal to .

Answer 2

Effective length of column fixed at both end as per IS 800 shall be  

Column’s length  :

• The distance between the two floors or the distance between the column’s fixed points (fixed or pinned), where all its movement is constrained in all directions is known as column’s length.
• We have already seen the case of a column with hinged at its both ends and in this case effective length of the column will be equal to actual length of the column.
• Now we will see the effective length of the column with one end is fixed and other end is free.
• We can easily say that effective length of the column will be equal to actual length of the column when both the ends of the column are attached. Le = L.
• Considering the above statement, we can briefly introduce the effective length in a more specific way and here it is.
• L = column length between pinned ends (inches) •
• As the column length increases, the critical load rapidly decreases (since it is proportional to L2), approaching zero as a limit.  
• The critical load at secure is referred to as Euler’s critical secure load. Euler’s equation is valid only for long, slender columns that fail due to secure.
