“…Note that the structural behavior related to the ultimate limit state of buckling of the C and Z90 profiles submitted to compression and bending around the major principal axis is the same [16,20]. Table 3 shows the critical and the characteristic resistance for the normal forces (N dist and N Rdist ) as well as for the bending moments (M dist and M Rdist ) arising from distortional buckling for galvanized shapes of the C sections.…”
