Only the sections which can be Class 3 or Class 4 when subject to pure bending are given in the table
* indicates that this parameter is not applicable to the section
F indicates that the section classification is controlled by the flange
Wel,eff,y is the minimum value of the effective elastic modulus about the y-y axis for a Class 4 section
Wpl,eff,y is the effective plastic modulus about the y-y axis for a Class 3 section

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

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.                                                                                        
NEd = Design value of the axial force.                                                                                        
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
