| Abstract | Bridge bearings are the structural members which are installed at the connection between superstructure and substructure of a bridge, thus it is crucial to maintain bearing functions as structural members. If bearing functions are declined, it is possible for the structure of the whole bridge to be changed and have an effect on functions of superstructure and substructure. Thus, maintaining functions of bearings is not negligible. Generally, "Visual inspection" is indicated as a standard method. However, it is difficult to evaluate the deterioration degree of bearing functions with "Visual inspection" only. Therefore, we have studied to establish a qualitative evaluation method regarding basic functions required for bridge bearings as structural members based on measuring displacement and strain. In this study, measuring displacement and strain in the bridge in north japan was carried out, and evaluating the deterioration degree of bearings with the evaluation method proposed was attempted. |
