Verification of resistance of cold formed cross-sections
Verification of cold formed cross-section for effect of buckling is provided by EN 1993-1-3 and chapter 6.2.5 (6.36) as follow:
where | Nb,Rd is the design buckling resistance of a compression member according to 6.2.2 (flexural buckling around main or geometric axis of symetry), | |
Mb,Rd is the lateral-torsional bending moment resistance according to 6.2.4 | ||
Mc,Rd is bending moment resistance according to 6.1.4.1, if lateral-torsional bucking doesn’t appears | ||
My,Ed and Mz,Ed including the effects of shift of neutral axis, if relevant. |
Verification of cold formed cross-section for effect of tension and lateral-torsional buckling is provided by EN 1993-1-3 and chapter 6.2.5 (6.36) as follow:
where | NRd is the design resistance of a cross-section for uniform tension |
