| Research Abstract |
This research deals with analytical procedure of seismic risk assessment applied to the railway system.
・Seismic system risk analysis is investigated for the railway facility, including fragility functions for viaducts and box-culvert and advanced seismic hazard analysis.
・Risk finance method such as earthquake insurance and derivatives are carefully examined for the railway facilities.
・System risk simulations with/without risk finance strategy are carried out for the railway system located in the Kanto region.
Through analytical research and simulated seismic system risk analyses, the author would like to make an emphasis that risk quantification is quite essential to the decision-making process in the catastrophe risk management.
