Question

What is the effective length of a column at both ends fixed?



a.
L


b.
L/2


c.
L/3


d.
2L​

Answer 1

Answer:

d. 2L

Explanation:

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 . The effective length factor is equal to 0.707.

When one end is fixed, with the other end let free in a column, the effective length is equal to Le=2L. The effective length factor is equal to 2.
