| Abstract: |
Seismic retrofit work for the Honshu-Shikoku Bridges has recently been launched because there is a concern that seismic risk for the bridges increases. In this paper, two examples of the investigation for seismic performance improvement using isolation and dissipation devices are described. One is the case of a viscous damper, which is adopted for a steel girder bridge. The other is the case of a seismic isolation bearing, which is adopted for a steel truss bridge. |
