How to Use This Calculator
- Enter the column unsupported length in feet and the effective length factor (K) for the end conditions.
- Input the modulus of elasticity and the moment of inertia for the chosen section.
- Set the applied axial load in kips.
- Review the Critical Buckling Load (Euler load) and the Slenderness Ratio.
- Check the Safety Factor - it should be 2.0 or greater per standard practice.
