Annual reliability index | Annual probability of failure | Damage state | Damage loss |
|---|---|---|---|
3.72 \(\le {\beta }_{a}\) | \({P}_{{f}_{a}}\le \) 0.0001 | Insignificant | \({C}_{R}\) |
3.09 \(\le {\beta }_{a}\)<3.72 | 0.001 \(\ge {P}_{{f}_{a}}\)>0.0001 | Minor | \({C}_{R}+{C}_{E}\) |
2.32 \(\le {\beta }_{a}\)<3.09 | 0.01 \(\ge {P}_{{f}_{a}}\)>0.001 | Significant | \({C}_{R}+{C}_{E}+{C}_{DP}+{C}_{IN}\) |
