Ultimate limit state
The verification equations differ according to the stress style.
Tension
Tension is verified in accordance with chapter 6.1.2. of EN 1995-1-1 using formula

Compression
Members in compression can be designed without or with consideration of buckling. Verification without buckling consideration is performed in accordance with chapter 6.1.4. using formula
Where is: | fc,0,d |
|
Verification with buckling consideration is performed in accordance with chapter 6.3.2. using formula
Where is: | kc |

The verification is performed at the edge of the cross-section, in the point of the most significant stress.
Verification with consideration of lateral torsional buckling uses these formulas
Where is: | kcrit,y, kcrit,z |
|
The bending is verified only in strong axis direction for built-up cross-sections.
Shear
Shear is verified in accordance with 6.1.7 using formulas

The verification is performed in the point of the most significant stress. Built-up cross-sections are verified in the centre of gravity.
The shear is verified only in strong axis direction for built-up cross-sections.
Combined bending and axial tension
Combined bending and axial tension is verified in accordance with chapter 6.2.3. using formulas
Combined bending and axial compression
Combined bending and axial compression is verified in accordance with chapter 6.2.4. using formulas
The verification is performed at the edge of the cross-section, in the point of the most significant stress.
Verification with buckling consideration is performed in accordance with chapter 6.3.2.
