Research on the implementation of bridge shock-resistant capability and Test Assessment Analysis Mode (2/2)

  • Date:2019-03-06
  • Update:2019-03-06
  • Department:IOT

Research result:

  • Based on the developed “Bridge Obstruction Testing Analysis Mode” being modified for this research, the bridge damage probability subjecting to varied seismic strength is diagnosed and estimated according to the existing bridge status.
  • Enhance the practicability of the “Mobile Vibration Test Mode” to measure, analyze and verify the vibration signal of the scene so as to establish the vibration signal critical frequency value after opening the bridge that has been blocked due to the earthquake or flushing hazard.

Troubleshooting:

  With the “Bridge Obstruction Testing Analysis Mode”, the Directorate General of Highways shall be able to assess the bridge damage probability after the earthquake in order to set the priority sequence of the bridge inspection and treatment so as to solve the problem where lots of bridges should be tested after the shock and where the bridge damage probability cannot be exactly controlled. After being verified, the “Mobile Vibration Testing Mode” can be used to solve the problem where the competent bridge management unit is unable to exactly control over the level of bridge safety after the earthquake or the flushing. In the meantime, it can also support the decision making on whether to open the bridge for traffic after the blockade.
