Table 3
The results of risk analysis (example).
| | Occurrence | Vulnerability | Final risk level | | Bridge cases | City classification | Types of lower road | Existence of bridge column within 9m of road verge | Distance from industrial complex | Truck accessibility to the road | Normalized occurrence | Service year | Safety level | Number of columns | Minimum diameter of column | Slenderness ratio | Design load | Normalized vulnerability |
| | A | Pass | 3 | 3 | 2 | 3 | 0.92 | 2 | 2 | 2 | 3 | 1 | 2 | 0.67 | RLH | | B | Fail | NA | NA | NA | NA | NA | NA | NA | NA | NA | NA | NA | NA | NA | | C | Pass | 3 | 3 | 1 | 3 | 0.83 | 2 | 1 | 2 | 1 | 2 | 2 | 0.56 | RLM | | D | Pass | 1 | 1 | 1 | 3 | 0.5 | 1 | 1 | 2 | 1 | 1 | 2 | 0.44 | RLL |
