What is Buckling?
Buckling is the sudden lateral failure of structural members under compressive loads. Our buckling calculator uses Euler’s formula to determine the critical load at which slender columns lose stability.
Buckling Formula
Euler’s critical load formula: Pcr = (π²EI)/(KL)²
| Variable | Meaning | Unit |
|---|---|---|
| E | Modulus of Elasticity | GPa/psi |
| I | Moment of Inertia | m⁴/in⁴ |
| L | Column Length | m/ft |
| K | Effective Length Factor | Unitless |
Practical Examples
Steel Column: E=200 GPa, I=0.0004 m⁴, L=5m, Fixed-Pinned (K=0.7)
Result: Critical Load ≈ 1,234 kN
Key Factors Affecting Buckling
- Column cross-sectional shape
- Material stiffness (Young’s modulus)
- End constraint conditions
- Length-to-thickness ratio
