Verification of resistance of cold formed cross-sectionsozarPosouzeniUnosnostTenkostenny
Verification of cold formed cross-section for effect of buckling in fire design situation is provided by EN 1993-1-3 and chapter 6.2.5 (6.36) as follow:
where | Nb,fi,Rd is the design buckling resistance of a compression member in fire design situation according to 6.2.2 (flexural buckling around main or geometric axis of symetry), |
Mb,fi,Rd is the lateral-torsional bending moment resistance in fire design situation according to 6.2.4 | |
Mc,fi,Rd is bending moment resistance in fire design situation 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 in fire design situation is provided by EN 1993-1-3 and chapter 6.2.5 (6.36) as follow:
where | Nfi,Rd is the design resistance of a cross-section for uniform tension in fire design situation |
