Application of a simulator to damage detection for bridge maintenance

摘要

Now, the structural health monitoring gives us more useful data by damage investigation. So, wehave to research what is important data for structural health monitoring, and study about usingmonitoring data to get a reasonable analysis data. In this paper, the concept of detecting damagewas proposed in long-term service bridges based on the study of applied "Traffic vibrationsimulator". That is new dynamic analytical technique applied to "substructure method". Thismethod has been used for a dynamic interaction problem with structures and vehicles moving overthem. This simulator results show not only a bridge and vehicle motion but also fatigue weak pointsabout all over the bridge. The conclusions of this paper give a good reference to detecting a moredetailed damage situation, and life time information by using this simulator result and structuralhealth monitoring data.
