| Design bending moment | My,Ed, Mz,Ed | kNm | Design values of the applied bending moments about the y-y and z-z axes. |
| Reduction area | Ared | mm² | The area to be deducted from the gross cross-sectional area to account for fastener holes, particularly in the tension zone. |
| k factor | k | - | Factor for the smoothness of the bolt holes. |
| Material factor | γM0 | - | Partial safety factor for resistance of cross-sections to yielding. |
| Material factor | γM2 | - | Partial safety factor for resistance of cross-sections in tension to fracture. |
| Cross-section class | - | - | Classification of the cross-section (Class 1, 2, 3, or 4). |
