  • Influence of passing vehicle effect for online estimation of highway bridge vibration characteristics by realization theory with wind-induced ambient vibration

抄録

Bridge dynamic characteristic estimation method with ambient vibration has been used in public recently as a bridge health diagnosis technique. Conventional studies by the authors showed that the vehicle-induced ambient vibration give harmfule effect for estimating low order-frequencies of the bridges by using realization theories. In this study, the authors conducted futher investigation on the tendency of the problems. The wind-induced or/and running vehicle-induced vibration data of existing arch bridge were used for series of simulation to evaluate the running vehicle effects. As a result, we cocluded that wind induced ambient vibration should be used for estimating dynamic characteristics of the objective bridge.
