| Outline of Final Research Achievements |
In this study, bridge inspection data of Nagasaki prefecture was analyzed and the correlation between survey items and soundness was evaluated. Similar data in other cities were analyzed and simple diagnostic methods that can be used by local governments were examined.
Next, in order to evaluate the rust appearance of weathering steel bridge, quantitative evaluation by image analysis was carried out. Furthermore, the bridge was faithfully modeled as a three dimensional analysis by photograph measurement. By taking pictures from all directions, three dimensional coordinates of the bridge were acquired and a three dimensional analytical model of the bridge was constructed.
