| Outline of Final Research Achievements |
In this study, the efficiency of vehicle response analysis technology for bridge health evaluation was verified. An vibration index which is very sensitive to a bridge damage is discovered, by using two sensors on the vehicle. Its sensitivity is examined by using the data obtained in numerical simulations, laboratory experiences and a field experiment. A technical issue, however, exists, which is the low applicability to the situation in which the road profile changes faster than the bridge.
