| λ | Slenderness coefficient |
| l0 | Effective length = kcr ⋅ l |
| i | Radius of gyration of the uncracked concrete section |
| kcr | Effective length factor = 0.5 ⋅ √[(1 + k1 / (0.45 + k1)) ⋅ (1 + k2 / (0.45 + k2))] according to 5.8.3.2(3) Formula (5.15) |
| l | Free length |
| k1, k2 | Flexibility coefficients at both ends of the element |
