Study on Mechanical Performance of Prestressed UHPFRC U-Beam Bridges
| Load range of single loading point | Load unit | Note |
| 0∼20 kN | 2 kN | Limit bearing capacity of the one-way slab, observe initial cracks | 20 kN∼50 kN | 5 kN | | 50 kN∼60 kN | 2 kN | Ultimate bearing capacity of the two-way slab, observe cracks | 60 kN to END | Displacement control | The deformation increases while the load application does not grow |
