| EMS98 | Damage level | Performance | Reparability | Ductility Ratio |
| 4 (5) | Heavy (collapse near collapse) | For columns and beams considered as primary components deformation exceeds three quarters (75%) of the ultimate value and at most one structural elements exceed the ultimate value | Hardly repairable or more often No repairable | 1.00 > DRCmax > 0.75 1.00 > DRBmax > 0.75 |
| 3 | Significant/ Medium Structural damage | For columns and beams considered as primary components the deformation not exceed three quarters (75%) of the ultimate value | Repairable More expansive | DRCmax 0.25 - 0.75 DRBmax 0.25 - 0.75 |
| 2 | Moderate/ Low Structural damage | For columns and beams considered as primary components the deformation not exceed 25% of the ultimate value | Easily repairable | DRCmax < 0.25 DRBmax < 0.25 |
| 1 | Weak No Structural damage | For columns and beams, the deformation not exceeds elastic limit. Only inter-storey drift-sensitive non-structural components are considered | Total | DRCmax < 1 DRBmax < 1 IDR < 0.1% |
