For bearing or buckling the web capacity = C1 + b1 C2 where b1 is the stiff bearing length
The beam component for end bearing assumes a sealing plate (thickness at least equal to the wall of the section) is welded to the end of the section by a continuous fillet weld

For values of the compression cross-sectional resistance, Nc,Rd, see values of Npl,Rd in tables for axial force and bending
✔ Items which are readily available in the UK market. Unticked items are subject to minimum order quantity and longer lead times.
* The section is a Class 4 section and values of Mc,Rd and MN,Rd are not calculated.
– Not applicable for Class 3 and Class 4 sections.                                                                        
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.                      

n = NEd / Npl,Rd
NEd = Design value of the axial force. 
Npl,Rd is the axial force resistance.

For values of the compression cross-sectional resistance, Nc,Rd, see values of Npl,Rd in tables for axial force and bending
✔ Items which are readily available in the UK market. Unticked items are subject to minimum order quantity and longer lead times.
* The section is a Class 4 section.

n = NEd / Npl,Rd

NEd = Design value of the axial force.

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.

Npl,Rd is the axial force resistance, which is equal to A fy and given in the cross-section resistance table.                                                                                        
Nb,Rd values in bold type indicate that the section is Class 4 and allowance has been made in calculating Nb,Rd
