+ HISTAR® yield strengths have been used in calculating capacities for this section

X Section becomes Class 4

$ For these values of n = N_Ed / N_pl,Rd the section would be overloaded due to N_Ed alone even when M_Ed is zero, because N_Ed would exceed the local buckling resistance of the section

– Not applicable for Class 3 and Class 4 sections

∗ The section can become Class 4 under axial compression only. Under combined axial compression and bending the section becomes Class 4 when the Class 3 N_Ed / N_pl,Rd limit is exceeded

N_Ed = Design value of the axial force

n = N_Ed / N_pl,Rd

The values in this table are conservative for tension as the more onerous compression section classification limits have been used

Under combined axial compression and bending the resistances are only valid up to the given N_Ed / N_pl,Rd limit. For higher values of n = N_Ed / N_pl,Rd the section would be overloaded due to N_Ed alone even when M_Ed is zero, because N_Ed would exceed the local buckling resistance of the section
