D14.C.6.3 Flexural Buckling - Axial Compression
Per section 13.3.1, the factored axial compressive resistance, Cr , of doubly symmetric sections conforming to the requirements of clause 11 for class 1, 2, or 3 sections shall be taken as:
Cr = ϕAfy(1+λ2n)-1/n
where= | ||
= |
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.
