| Research Abstract |
In order to create quantitative, objective and effective method maintaining civil infrastructures, this research aims to develop monitoring nodes which realize high-density measurements for them. A monitoring system, which combines a laser Doppler vibrometer with a Total Station for surveying, was applied to existing cable-stayed bridges. As a result, it was confirmed that the system made possible to realize remote and automated monitoring for bridges. Moreover, monitoring nodes using MEMS based technologies were developed. Their application test to vibration measurement of a bridge revealed that the nodes were possible to replace conventional measurement system.
