Relationship between the failure modes of test beams and the corresponding failure types.
| | Group | Beam no. | Failure mode | Failure type |
| | SPF-1.1 | SPF-1.1 (1) | Steel bar defect | Type No. 1 | | SPF-1.1 (2) | The lowermost laminate breaks | Brittle tension failure | | SPF-1.1 (3) | The lowermost laminate breaks |
| | SPF-1.2 | SPF-1.2 (1) | — | Type No. 1 | | SPF-1.2 (2) | Tension failure of the beam bottom | Brittle tension failure | | SPF-1.2 (3) | Tension failure of the beam bottom |
| | SPF-1.3 | SPF-1.3 (1) | — | Type No. 2 | | SPF-1.3 (2) | Compression failure of the beam top | Ductile tension failure | | SPF-1.3 (3) | Ductile tension of the beam bottom |
| | SPF-2.2 | SPF-2.2 (1) | — | Type No. 1 | | SPF-2.2 (2) | Tension failure of the beam bottom | Brittle tension failure | | SPF-2.2 (3) | Tension failure of the beam bottom |
| | SPF-3.2 | SPF-3.2 (1) | Breakage of the beam-end | Type No. 2 | | SPF-3.2 (2) | Tension failure of the beam bottom due to the beam-end breakage | Ductile tension failure | | SPF-3.2 (3) | Tension failure of the beam bottom due to the beam-end breakage |
