Abstract
In this paper, the procedure for estimating the reliability of bridges and embankments subjected to ground motion and tsunami caused by the anticipated Nankai Trough earthquake is presented. Occurrence of a large earthquake along the Nankai Trough and the subsequent giant tsunami are predicted in Japan and it is expected that the damage and the economic loss caused by the event are more severe than those caused by the 2011 Great East Japan earthquake. In an illustrative example, reliabilities of bridges and embankments in Owase City, where the effects of both seismic shaking and the tsunami waves due to the anticipated Nankai Trough earthquake would be very intense, are compared to identify the structures with the lowest reliability and significant hazard.
