∗ The section may be Class 4 under axial compression

Values in italic type indicate that the section is a Class 4 section in pure compression and allowance has been made in calculating the resistance

For values of the compression cross-sectional resistance, N_c,Rd, see values of N_pl,Rd in tables for axial force and bending
