# D14.C.6.3 Flexural Buckling - Axial Compression

Per section 13.3.1, the factored axial compressive resistance, C_{r}
, of doubly symmetric sections conforming to the requirements of clause 11 for class 1, 2, or 3 sections shall be taken as:

C_{r} = ϕAf_{y}(1+λ^{2n})^{-1/n}

= | ||

= |

Doubly symmetric sections which may be governed by torsional-flexural buckling shall also meet the requirements of 13.3.2.

The parameters `KY`, `LY`, `KZ`, and `LZ` are applicable for this.
