Classification of cross-section chord For the classification of the cross-section, it’s necessary to know the distribution of the normal stresses. EN 1993-1-1 Table 5.2 Sheet 2 of 3 For the web we consider a uniform stress equal to: A N Ed w   = -250,34 N/mm 2 For the flanges we have: i yy Ed Ed i I v M A N    Where v i is the position of the considered fibre. And for the upper part ( Z > 0) of the flange: 2 f 1 / v b  and r t v   2 2 w 1  = 180,91 N/mm 2 , 2  = 245,62 N/mm 2 And for the inner part ( Z < 0) of the flange:   2 f 1 / b v   and   r t v    2 w 2 1  = 319,78 N/mm2, 2  = 255,06 N/mm 2 In view of these results, the cross-section being all over in tension is considered of class 1.
