Verification of axial stress in solid cross-sections
The axial stress in the cross-section may be caused by axial force N, bending moments My, Mz and bimoment B. The combination of these forces and moments is verified.
The verification without consideration of buckling and lateral torsional buckling is done according to the following expression for the classes 1 and 2:
The expression for the class 3:
The expression for the class 4:
Where is | Nθ,Rd |

Mc,Rd,y, Mc,Rd,y |

If the shear verification fails for particular directions y and z, the value 1.0 is used for corresponding direction in equations described above.
