Question

The effective length 'L' of a column hinged at both ends as compared to its actual length l is-

• A. $$L=I/2$$
• B. $$L=I$$
• C. $$L=2I$$
• D. $$L=2I^2$$

Answer 1

Answer:

$$L=I$$

The effective length of a column hinged at both ends is equal to its actual length. The buckling load can be calculated using Euler's column formula which depends on the effective length. For both end hinged columns, the effective length is equal to the actual length. Therefore, option 2 is the correct answer. The formula for effective length is $L_ {eq} = L / n$ . where n is the constant factor depending on the boundary conditions.
