Table 1 Relation of damage category and limiting tensile strain, according to Boscardin and Cording (1989)
From: Window detection in facade images for risk assessment in tunneling
Category of damage | Degree of severity | Limiting strain [%] |
|---|---|---|
0 | Negligible | 0−0.05 |
1 | Very slight | 0.05−0.075 |
2 | Slight | 0.075−0.15 |
3 | Moderate | 0.15−0.3 |
4 | Severe | ≥0.3 |
