Abstract
In this study, we propose a procedure for constructing seismic vulnerability functions of elevated railway based on case histories of elevated railway structures damaged by past earthquakes. Damage rates at each seismic intensity level in the 1995 Southern Hyogo Earthquake and the 2011 Great East Japan Earthquake are calculated. The results indicate that (1) slight damages on structures of elevated railways appear from the JMA seismic intensity 5- and heavy damages appear from the JMA seismic intensity 6-, (2) heavy damage rates in the 2011 Great East Japan Earthquake are lower than that in the 1995 Southern Hyogo Earthquake, (3) slight damage rates in the 2011 Great East Earthquake are higher than that in the 1995 Southern Hyogo Earthquake, (4) total damage rates in the 2011 Great East Japan Earthquake are comparable with that in the 1995 Southern Hyogo Earthquake.
