Displacements and axial forces of the three structural models under longitudinal bridge excitation.
| Structure type | Maximum displacement of the tower top (mm) | Maximum displacement in the middle of the span (mm) | Maximum axial force in the middle of the span (kN) | Cross bridge | Longitudinal direction | Vertical | Cross bridge | Longitudinal direction | Vertical |
| Model 1 | 0 | 39.51 | 61.30 | 0.071 | 1.76 | 54.59 | 2.37 × 104 | Model 4 | 0 | 39.70 | 61.39 | 0.070 | 1.80 | 6.15 | 1.80 × 104 | Model 5 | 0 | 39.21 | 61.58 | 0.083 | 1.70 | 0.37 | 2.94 × 104 |
