For a prismatic column with one end fixed and the other end pinned, which effective length factor is used in Euler buckling analysis?
Correct answer: B. 0.70
- A. 0.50
- B. 0.70
- C. 1.00
- D. 2.00
Explanation
A fixed-pinned column has an effective length factor of approximately 0.70, more precisely about 0.699. The value is lower than that of a pin-ended column because the fixed end provides greater rotational restraint.

The more specific you are, the faster it gets fixed. A source beats an opinion.

About Structural Analysis
Structural analysis determines how beams, frames, trusses and arches carry loads through reactions, shear forces, bending moments, axial forces and deflections. It covers free-body diagrams, equilibrium equations, determinacy, influence lines and methods such as slope deflection, moment distribution and virtual work, while distinguishing analysis of a structure from its design.
