Flexural Buckling Limit State
The buckling deformations (deflections) all lie in one of the principal planes of cross section. No twisting of the cross section occurs for flexural buckling.

For the calculation of reduction factor, the imperfection factor should be determined depending on buckling curve according to Table 6.1. There are five different buckling curve in EN 1993-1-1 Figure 6.4. To select buckling curve of the cross section is determined according to Table 6.2.
