Effect of As-Built versus Retrofit
Schematic plot of probability of damage as a function of earthquake intensity for: minor damage; moderate damage; major damage, for both the as-built and retrofit cases. As-built shown with solid lines represent the "do nothing" solution. The dashed lines define performance in a retrofitted condition. This allows a determination to be made as to when retrofit is required as a function of the level of damage that is acceptable. Only the 2% EQ (probability of exceedance in 50 years or 2,500-year event) and 10% EQ (probability of exceedance in 50-years or 500 years event).
Probability of Damage (%)
| | 10% EQ | 2% EQ |
|---|
| As-built |
|---|
| Minor Damage | 58 | 96 |
|---|
| Moderate Damage | 26 | 84 |
|---|
| Major damage | 0 | 58 |
|---|
| Retrofit |
|---|
| Minor Damage | 62 | 98 |
|---|
| Moderate Damage | 8 | 38 |
|---|
| Major Damage | 0 | 25 |
