Calculation scheme of controlling variable method of different interface parameters.
| Fortification intensity | Frequent ground motion | Basis ground motion | Rare ground motion | Extremely rare ground motion |
| VIII degree | 0.13 g | 0.4 g | 0.746 g | 1.08 g | Exceeding probability | 50-year 63% | 50-year 10% | 50-year 2% | 100-year 1% |
