| Outline of Final Research Achievements |
Deterioration and aging of bridges structures and damage caused by strong earthquakes might be conducive to collapse of the bridge, sometimes with catastrophic consequences. Therefore,investigation of structural condition of bridges is necessary for secure safe road operations. This paper presents a prototype of piezoelectric-cable sensor for vibration monitoring system that permits easy evaluation of the bridge structure integrity. For this study, a bridge located at Yurihonjo city, Japan was chosen as a target structure. The experiment was performed using a track of 19 t of equivalent weight. Responses were captured appropriately using the proposed system. They are comparable to responses obtained using accelerometers. Although the general response pattern is obtained appropriately, it is necessary to improve the accuracy of the proposed system to gather more reliable data.
