Abstract
Damage of bridges suffered from the 2011 Great East Japan Earthquake was overviewed based on the statistic analysis. In this paper, the bridges built near the Tobu viaduct in the Sendai Tobu Highway were analyzed, because a significant ground motion was recorded near the Tobu viaduct and the laminated elastomeric bearings in the viaduct were ruptured due to the ground motion effect. It is found from the data analysis that characteristic of damage level depends on the structural type of bridges. For example, damage of single-span simple girder bridge supported by abutments was less significant than multi-span simple girder bridge. Furthermore, it was found that there were few ratios of the damage to bridge columns which was remarkably observed during the 1995 Kobe Earthquake, while the damage was observed at bearing supports during the 2011 Great East Japan Earthquake.
