Abstract

<p>Social infrastructures such as roads, bridges, and tunnels are aging, and its maintenance and management are an urgent issue. The goal of this study was to estimate the deformation, fatigue, and deterioration of bridges, by using digital twin model. To accomplish this, first, we modeled of entire existing long bridge with 3D shell and solid elements. Next, we estimated the deformation of the bridge under vehicle load and daily temperature change by applying linear static analysis. The numerical results were within the 95% confidence interval of the actual measurement, in the case of vehicle load. Further, the model could qualitatively represent the deformation of the bridge under daily temperature change.</p>
