Prediction of traffic vibration and fatigue damage of bridges

Traffic vibration analysis August 22, 2014

Analyzes the vibration of an arbitrary point in consideration of the structure of the bridge, the unevenness of the road surface, and the type and size of vehicles, etc. This makes it possible to predict either the actual or a high-precision estimate of fatigue damage, a task that was previously difficult.

System Features

  • Applicable to all road bridges regardless of bridge type
  • Applicable to studies of environmental vibration countermeasures such as ground vibration and low frequency air vibration
  • Applicable to structural studies on pedestrian usability of bridges
  • Applicable to studies of fatigue countermeasures for steel members such as steel bridges and sign posts
  • Checking of capacity and durability is possible as an alternative to stress frequency measurements of existing bridges

The system answers the following needs:

  • We want to take measures against environmental problems such as ground vibration and low frequency air vibration.
  • We want to respond to the problem of fatigue damage on accessories such as lampposts and steel bridges only by analysis.
