• Verification of estimated accuracy of natural frequency affected by wind velocity by bridge remote monitoring

抄録

Fundamental study to diagnosis health condition of the bridge has been performed with the ambient vibration with structural identificaion theoryies. However, accuracy estimation of bridge dynamic characteristics may not be possible when the bridge is not well excited. Therefore, it is necessary to extract relatively high amplitude vibration data and evaluate the characteristics of the ambient vibration beforehand to apply structural health monitoring. This study pays attention to environmental factor against the accuracy of estimated dynamic characteristics such as wind velocity. Developed remote monitoring system with wind velocity triger function were applied to the existing bridge and the estimation accuracy corresponding to the wind velocity was verified.
