Change of DDF at different load stages.
| Original condition | State | Concentrated load (kN) | Load distribution factor of beam #1 |
| Intact bridge | Linear range | 0∼50 | About 0.30 | Near linear range | 50∼118 | 0.30∼0.32 | Maximum load applied | 147 | 0.54 | Damaged bridge | Ultimate capacity | 131 | 0.70 | “Single Plate Load Effect” appeared | 102 | 0.84 |
