X Section becomes Class 4
$ For these values of n = NEd / Npl,Rd the section would be overloaded due to NEd alone even when MEd is zero, because NEd 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 NEd / Npl,Rd limit is exceeded
NEd = Design value of the axial force
n = NEd / Npl,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 NEd / Npl,Rd limit. For higher values of n = NEd / Npl,Rd the section would be overloaded due to NEd alone even when MEd is zero, because NEd would exceed the local buckling resistance of the section
