Table 4
Comparison of seismic mitigation ratios with different measures.
| Restraint systems | Longitudinal displacement at the girder end (%) | Longitudinal displacement at the tower top (%) | Base shear in tower | Base moment in tower (%) |
| ECD | 32.74 | 28.10 | -9.98% | 0.32 | VD | 45.97 | 33.20 | 18.69% | 19.15 |
