Hysteretic behavior models under consideration.
| Hysteretic model | Postyielding stiffness (%) |
γ (strength degradation) | γ (stiffness degradation) | E NC | Description |
|---|---|---|---|---|---|
| EP | 0 | 0 | 0 | 9 | Nondegrading EP model |
| B5D10 | 5 | 0.321 | 0.152 | 7.5 | Strength degradation and low stiffness degradation typical of steel structures |
| B5D30 | 5 | 0.321 | 0.515 | 5.6 | Strength degradation and moderate to large stiffness degradation typical of reinforced concrete structures |
