| Abstract: | The metal fracture analysis is made for the U-shaped bolts collected in the existing railway concrete bridges; and some vibration tests are also done on the 1.55m-span bracket of pedestrian sidewalk during a train is passing. The results show that U-shaped bolts had been enduring repeated action during the trains' passing and caused fatigue destroy,and the renovating method for the anchor system is also put forward. |
| Keywords: | U-shaped bolts fracture analysis vibration test fatigue damage |
