Description
<p>Periodical visual inspection has been started in Japan. According as the amount of inspection data increases, consistent and traceable data management is crucial. Digital transformation plays a very important role. We are developing 3D models in which inspection data can be saved. Additionally, we are also developing structural 3D model by the finite element analysis, integrating the monitoring data for the smart infrastructure management. An existing bridge was picked up in Tokyo area. Comparison between finite element analysis and field loading was made. Agreement between field loading and analysis is very important because of the simulation of deterioration on the structure is very crucial. The influence of appendages such as fense, covering plate to the stiffness of the structure was not negligible. Considering those, the accuracy was improved up to 92.7%. The error of the analysis was corresponding to 1 MPa by stress value. By the use of numerical model of finite element analysis, prediction of the weak points is the next step.</p>
